Laboratory casework refers to the cabinets, shelving, and storage systems designed specifically for scientific environments, where durability, chemical resistance, and compliance with safety standards matter far more than aesthetics. Unlike standard residential or office cabinets, lab casework is built from materials such as steel, wood, phenolic resin, or polypropylene that can withstand daily exposure to chemicals, moisture, and heavy loads. LOC Scientific designs and supplies casework for universities, research institutions, pharmaceutical facilities, and industrial labs, serving clients across a wide range of industries from our Buford, GA base.

The best material depends on your lab environment, the chemicals in use, and your budget. Steel casework is durable, widely used, and cost-effective for most general lab settings. Wood casework offers a warmer aesthetic and works well in lower-chemical environments such as classrooms. Phenolic resin and polypropylene casework provide superior chemical and moisture resistance for demanding environments, while stainless steel is preferred for cleanrooms and high-sterility applications. Plastic laminate casework is another option well suited to light-duty environments where appearance and affordability are priorities. LOC Scientific offers all major casework materials and helps clients select the right option based on their specific lab requirements.

Metal lab cabinets are the most common choice for general research and institutional settings because they are strong, easy to clean, and competitively priced. Wood casework works well in teaching labs or office-adjacent spaces where chemical exposure is minimal. Phenolic resin cabinets are a better choice for environments with frequent chemical exposure, high humidity, or wet conditions, since the material is non-porous and highly resistant to corrosion and staining. Plastic laminate is a lighter-duty option that suits administrative or support spaces connected to lab areas. LOC Scientific's design team can evaluate your lab's usage profile and recommend the right material combination for your specific project.

Key design factors include the types of chemicals and materials that will be stored or used, the workflow and traffic patterns within the lab, required storage capacity, ADA accessibility requirements, and the need for built-in utilities such as sinks, fume hood connections, or electrical outlets. Lab casework also needs to account for the weight loads of stored equipment, the frequency of cleaning, and long-term flexibility as research needs change. LOC Scientific provides full laboratory design services and works with facility managers and architects to develop casework layouts that meet both functional and compliance requirements.

Laboratory casework must comply with applicable OSHA regulations, NFPA standards for flammable storage, and institutional requirements set by the facility or funding agency. Specific standards vary by cabinet type. For example, flammable storage cabinets must meet OSHA 29 CFR 1910.106 requirements and NFPA 30 guidelines. Biological safety cabinets are governed by separate NSF/ANSI 49 certification standards. LOC Scientific supplies casework that meets relevant industry standards and can provide documentation for compliance review as part of the project process.

Fixed casework is built into the lab and attached to walls or floors, providing a permanent, stable setup that maximizes storage in a defined footprint. Modular casework is freestanding and reconfigurable, allowing labs to adapt their layout as research programs evolve without major construction. Modular systems are increasingly popular in flexible or multi-use lab environments where space needs change frequently. LOC Scientific offers both fixed and modular casework solutions and can help clients determine which approach best fits their space and long-term operational needs.

Laboratory casework costs vary significantly based on material selection, configuration complexity, quantity, and whether custom fabrication is required. Steel casework is generally the most affordable option, while stainless steel and phenolic resin systems carry a higher price point due to material costs and manufacturing complexity. Project factors such as site conditions, installation requirements, and lead time can also affect the final cost. LOC Scientific provides detailed project quotes and works with clients to find solutions that meet both performance requirements and budget constraints.

Selecting the right fume hood requires evaluating the types and quantities of chemicals being used, the hazard level of the work, the available ductwork and HVAC infrastructure, space constraints, and energy efficiency goals. High-hazard applications involving strong oxidizers, carcinogens, or radioactive materials require specialized hood types rather than standard ducted units. LOC Scientific's team works directly with lab managers and safety officers to assess these factors and recommend the fume hood configuration that provides the appropriate level of protection while meeting facility and budget requirements.

Laboratory fume hoods must comply with ANSI/AIHA Z9.5, the primary consensus standard governing laboratory ventilation in the United States, which sets requirements for hood design, face velocity, performance testing, and maintenance. OSHA regulations under 29 CFR 1910.1450 also require that engineering controls such as fume hoods be used and maintained appropriately for chemical hazard control. LOC Scientific fume hoods meet ANSI/AIHA Z9.5 and SEFA standards and are factory-tested to ASHRAE 110, with performance documentation available for compliance purposes.

Annual certification by a qualified professional is required by ANSI Z9.5 and NFPA 45. That hour-long test measures face velocity, containment, and alarm function. But smart labs also do a 30-second daily walk-through: check the sash moves smoothly, the airflow monitor shows green, and no clutter blocks the baffles or exhaust slot. 

Every six months, inspect the blower belt and motor bearings. LOC Scientific hoods are built for easy service access — no special tools needed to reach the plenum or baffle screws. Call us for a printable daily inspection log you can hang on each hood.

Ducted hoods exhaust hazardous air completely outdoors. Ductless hoods pass air through filters and return it to the lab. Ducted is the gold standard for safety — it removes everything, has no filter saturation risk and no ongoing filter replacement cost. But it requires building exhaust ducts and make-up air, which can be expensive to install. 

Ductless is cheaper to install (no ductwork) and portable, but filters must be changed regularly (roughly 500-500-1,000 per set), and they only work for low-hazard, known chemical loads. LOC Scientific sells both but will tell you plainly: if your work involves unknown or high-toxicity chemicals, go ducted. Send us your chemical inventory; we'll calculate whether a ductless hood's carbon bed can handle it.

Improper airflow turns your protective barrier into a hazard. A hood must maintain face velocity between 100 and 125 feet per minute (fpm) on average. Too low (under 80 fpm), and contaminants roll out into your breathing zone. Too high (over 150 fpm), and turbulence pulls fumes back toward you. 

Even at the correct average, poor baffle design or cross-drafts from nearby windows, doors, or HVAC diffusers can create local hot spots where containment fails. LOC Scientific hoods are tested for uniform face velocity across the entire sash opening, not just one center point. Have an existing hood with suspected airflow issues? Send us a video of a smoke test; we'll diagnose it remotely at no charge.

Start by evaluating what happens in your lab: the chemicals in use, the equipment that needs support, and how people actually move through the space. From there, prioritize materials that can handle those specific exposures, casework that keeps things organized without getting in the way, and worksurface heights that reduce strain during long hours. 

The real key is working with a partner who understands lab workflows, not just furniture specs. Unlike many suppliers who push catalog items, LOC Scientific designs each layout around your unique processes. Send us your floor plan – we’ll provide a custom furniture recommendation within 24 hours.

Epoxy resin offers the highest chemical and heat resistance – it withstands acids, alkalis, and temperatures up to 600°C, making it ideal for industrial and chemical labs. Phenolic resin delivers excellent chemical and moisture resistance at a more accessible price point, perfect for general lab use. 

Stainless steel excels where sterilization is critical, such as microbiology or pharmaceutical labs. Polypropylene is another strong option for wet labs handling aggressive acids. Every lab is different, so the right material is the one that matches your specific chemical exposure and workflow.

SEFA (Scientific Equipment and Furniture Association) standards are the industry benchmark for lab furniture safety and durability. These cover everything from fume hood performance (SEFA-1) to casework load capacity and chemical resistance (SEFA-8). While not legally mandated, institutional buyers and facility planners often require SEFA compliance. 

LOC Scientific furniture complies with recognized SEFA standards, giving you confidence that your lab meets rigorous safety and quality benchmarks. View our USA-made, SEFA-compliant casework specifications here.

Modular furniture uses pre-engineered components that can be reconfigured as your lab evolves, offering faster setup and greater long-term flexibility. Custom furniture is built for a specific space and workflow, providing a perfect fit but less adaptability down the road. Modular systems typically deliver 30% faster than bespoke fabrication and use the same high-grade materials. 

However, some labs require custom dimensions or unique configurations that only a tailored solution can provide. At LOC Scientific, many of our projects blend both approaches – we customize within modular systems to give you the best of both worlds.

With proper maintenance, quality laboratory furniture lasts 15 to 25 years. Labs with excellent housekeeping can see 20+ years of service, while heavy-use or poorly maintained environments may fall closer to the 10-15-year range. The biggest factor is material quality and daily care – wiping up spills promptly, avoiding unnecessary impact, and following manufacturer guidelines. 

LOC Scientific builds all furniture in the USA using high-grade materials to maximize your investment over the long haul. Call our design team for maintenance tips that extend the life of your lab.

The type of chemicals being used is your starting point. Acid digestion requires different liner materials than solvent work or perchloric acid applications. Next, consider face velocity requirements (typically 100 fpm under ANSI Z9.5 standards), exhaust system compatibility (constant air volume vs. variable air volume), and the hood's physical placement in your lab – it should be more than 10 feet from any exit doorway. 

Also factor in long-term operating costs: high-performance hoods can reduce energy consumption significantly. LOC Scientific will help you match a hood to your exact application and budget.

Proper ventilation is the difference between a safe lab and a hazardous one. Fume hoods capture and exhaust harmful vapors before they reach breathing zones, but even open bench areas benefit from good airflow to dilute airborne contaminants. 

Furniture placement matters too: tall cabinets or casework can disrupt air patterns and create dead zones where contaminants accumulate. That's why LOC Scientific considers HVAC integration from the first design sketch. Smart furniture layouts work with – not against – your ventilation system. Send us your lab's airflow requirements, and we will design a layout that keeps everyone safe.

Metal lab casework is the heavy-duty cabinet system made from steel panels with a chemical-resistant powder-coated finish, purpose-built for harsh lab environments. Unlike standard office cabinets, it integrates seamlessly into the lab to provide durable, secure storage for chemicals, glassware, and tools, also supporting countertops and equipment. 

Research, education, healthcare, and quality control labs all rely on metal casework as the sturdy, sanitary foundation for their daily workflows.

Metal cabinets deliver the best all-around combination of strength, cost-efficiency, and chemical resistance for most labs. Compared to wood, they far surpass in moisture and fire resistance. While phenolic offers unmatched chemical protection, powder-coated steel provides comparable defense against common lab spills and impacts at a lower upfront investment. It is the standard choice for roughly 80% of the commercial market. 

For demanding sterile or high-moisture settings, our stainless steel options offer ultimate longevity. Many imported brands cut corners here. We build all our casework in the USA so you get a best-in-class balance of durability and value. We would be happy to discuss the best material for your application and budget.

Yes, modern metal lab cabinets with a chemical-resistant powder-coated finish are highly resistant to most common lab chemicals (dilute acids, bases, solvents), moderate heat, and corrosion. The non-porous powder coating is also abrasion and corrosion-resistant. However, it is important to know that if the coating is chipped, the exposed steel can be vulnerable, and concentrated strong acids may attack the coating over time. 

For aggressive high-acid or wet applications, LOC Scientific can guide you towards high-grade stainless steel as a more robust alternative. To ensure the best fit for your chemical inventory, send us your chemical list for a collaborative material review.

Any lab that needs tough, affordable storage without constant babysitting. That includes high-throughput QC labs, university teaching spaces, and hospital satellite labs. Here's where metal casework genuinely outworks other materials:

• Quality control labs - Running dozens of samples daily means drawers get opened hundreds of times. Metal holds up.
• Teaching labs - Students spill, bump, and overload. Powder-coated steel survives where phenolic chips and wood swells.
• Pharmaceutical R&D - Frequent solvent use and sterilization wipes. Metal's sealed surfaces clean easily without degradation.
• Forensics and crime labs - Evidence storage demands security and chemical resistance without stainless steel's price tag.

What metal does not love: standing water, strong hydrofluoric acid, or autoclave heat. For those, we will steer you toward phenolic or stainless steel. LOC Scientific will not sell you metal just because we make it. We'll ask about your actual chemical inventory, cleaning protocols, and budget first. Call us with your lab type, and we'll tell you honestly if metal is your answer or overkill.

Metal lab cabinets support safety by being designed and tested to meet rigorous SEFA (Scientific Equipment and Furniture Association) standards. Compliance with the SEFA 8M standard for metal casework is a key benchmark for quality and safety. It ensures the cabinets have passed intense performance tests, including bearing heavy loads, enduring thousands of drawer cycles, and resisting chemical staining and damage. 

When you choose SEFA-compliant cabinets, you know they are built to contribute to a safer, more durable lab environment. All LOC Scientific metal casework is SEFA-compliant, making your lab safety review process smoother.

Absolutely. Metal lab casework is highly customizable, and its inherent strength allows for various configurations often not possible with other materials. Modern metal casework can be configured as base, wall-mounted, or tall units in nearly any size. Inside, you can further customize with adjustable shelves, removable backs, and specialized drawer configurations. 

The most significant choice is between modular systems, which offer maximum future adaptability, and fixed installations for a permanent, seamless look. LOC Scientific prides itself on designing a solution, not just selling a product. From standard specs to fully custom dimensions and layouts, we tailor everything to your specific footprint. Contact us for a free layout consultation to plan your ideal lab configuration.

Metal lab cabinets are exceptionally durable, with many industry experts noting they can last as long as the laboratory itself or a solid 25+ years. This long lifespan makes them a cost-effective investment. Their maintenance is also minimal compared to other materials. The non-porous, powder-coated steel surfaces are easily cleaned with a soft cloth and mild detergent. 

However, to maintain the integrity of the protective coating against rust, you should never use abrasive pads, strong bleach, or harsh solvents on the painted surfaces. LOC Scientific cabinets are engineered for decades of reliable service, and we are always available to guide you on proper care to protect your investment.

Stainless steel cabinets are used wherever cleanliness, durability, and corrosion resistance are non-negotiable: pharmaceutical production, biological research, hospital settings, and food science labs. They safely store everything from sensitive biological samples and reagents to sterile instruments and flammable materials. Their non-porous surface resists bacterial growth and stands up to harsh cleaning agents and frequent wash-downs. 

Unlike many import brands, LOC Scientific builds all our stainless steel cabinetry in the USA to your exact specifications. Send us your lab’s layout, and we will design a custom storage solution for your specific application.

Unlike epoxy or phenolic which can scratch, stain, or degrade over time, stainless steel offers the best combination of cleanability and brute strength for demanding lab environments. While epoxy resin leads in chemical resistance and phenolic is a budget-friendly option, they are not suitable for autoclaving or may degrade with heavy moisture exposure. 

Stainless steel is sterilizable, non-porous, and resists bacterial growth. LOC Scientific guides you in selecting the right material to ensure your cabinets align with your lab’s specific workflow and required performance. View our full line of USA-made stainless steel casework here.

The choice comes down to 304 for general-purpose use or 316 for maximum corrosion resistance, especially against chlorides (bleach, saline). Grade 304 (18% chromium, 8% nickel) is the standard “workhorse” for most labs. Grade 316 adds 2-3% molybdenum, giving it superior protection against pitting from harsh chemicals and salt exposure—critical for coastal facilities or labs handling corrosive solvents. 

Most suppliers default to lower-grade imports. LOC Scientific builds with premium USA-sourced stainless steel and helps you select the grade that fits your budget and environment. Call our team to discuss which grade matches your chemical inventory.

Yes, but with important caveats. Stainless steel performs well against most lab reagents and cleaning agents, yet it is not impervious to all chemicals. It offers good resistance to a wide range of chemicals, including common acids and alkalis. However, strong mineral acids like hydrochloric (HCl) or prolonged exposure to chlorides can cause pitting corrosion. 

Unlike many suppliers that make broad claims, LOC Scientific provides honest, expert guidance on where stainless steel excels and where another material may be better. Send us your chemical compatibility list, and we will recommend the right cabinet material for your safety.

Their non-porous, seamless surface prevents particle shedding, resists microbial growth, and can be sterilized repeatedly without degrading. This makes them essential for aseptic processing, sterile storage, and any environment requiring stringent contamination control. 

A proper cleanroom-grade cabinet features radiused corners and precision welds to eliminate hidden areas where contaminants can accumulate. When you choose LOC Scientific, you don’t just get a cabinet; you get a partner. We work with you to ensure your storage solution helps maintain the highest level of cleanroom compliance.

Along with pharmaceutical, healthcare, and food/beverage companies, stainless steel cabinets are also standard in research labs, higher education facilities, and clinical testing centers. Here is where you will typically find them:

• Pharmaceutical & Biotech: Storing raw materials, in-process samples, and finished drugs
• Healthcare & Clinical Labs: Housing sterile supplies, instruments, and biological specimens
• Higher Education: Teaching and research labs requiring durable, safe, and easy-to-clean storage
• Food & Beverage: Wet processing areas demanding high sanitation
• Analytical & Quality Control: Protecting sensitive test procedures from contamination

No matter the industry, LOC Scientific delivers custom, USA-made solutions tailored to your specific compliance and workflow needs. Send your floor plan for a free, no-obligation storage layout consultation.

For routine cleaning, use a soft cloth with warm water and a mild detergent (or isopropyl alcohol), wiping in the direction of the grain to protect the finish. This simple practice removes residues and prevents streaks. Never use steel wool, abrasive pads, or cleaners containing bleach/chlorine—they scratch the surface and compromise the protective chromium oxide layer, leading to corrosion. 

For a deeper clean, use a dedicated neutral-pH cleaner or an isopropyl alcohol solution. LOC Scientific cabinets are engineered for easy maintenance, but we also provide lab-deep guidance to help your staff keep your installation in peak condition for decades.

The most common laboratory countertop materials are epoxy resin, phenolic resin, and stainless steel. Epoxy resin is widely used for its excellent chemical resistance and durability in general research and teaching labs. Phenolic resin offers a hard, smooth surface with good resistance to heat, moisture, and everyday lab chemicals. Stainless steel is preferred in cleanrooms, food science, and high-sterility environments. LOC Scientific supplies all three countertop materials and helps clients select the right surface for their specific application.

Epoxy resin countertops are cast from a thermosetting polymer that provides excellent resistance to a broad range of chemicals, heat, and physical impact, making them a popular choice for general research, teaching, and analytical labs. Trespa TopLab phenolic resin countertops are made from layers of kraft paper saturated with phenolic resin and compressed under high heat, resulting in a hard, smooth surface that resists moisture, heat, and many common lab chemicals. Epoxy resin typically offers superior chemical resistance for highly corrosive environments, while Trespa TopLab phenolic resin is a cost-effective option for labs with moderate chemical exposure. LOC Scientific carries both materials and can provide samples and specifications to support your selection.

Epoxy resin countertops offer the broadest and strongest chemical resistance of the standard laboratory countertop materials, making them the preferred choice for labs working with strong acids, bases, solvents, and other corrosive substances. Stainless steel also performs well against many chemicals but can be vulnerable to certain acids and chlorides. Phenolic resin offers good resistance to common lab chemicals but is generally considered less robust than epoxy resin in high-exposure environments. LOC Scientific can provide detailed chemical resistance charts for each material to help you make an informed selection.

Yes. Epoxy resin countertops are non-porous and highly resistant to moisture absorption, making them a reliable choice for wet labs, sink areas, and environments where water and liquid exposure is frequent. They do not warp, swell, or delaminate under normal wet lab conditions, unlike some wood-based countertop materials. LOC Scientific's epoxy resin countertops are manufactured to meet the demands of high-moisture lab environments and are compatible with integrated or drop-in laboratory sinks.

Most laboratory countertops, including epoxy resin and phenolic resin, should be cleaned with mild detergents or lab-safe disinfectants and wiped dry after each use to prevent staining and buildup. Avoid abrasive cleaners or scrubbing pads that can scratch the surface over time. Phenolic resin surfaces may require periodic treatment per manufacturer guidelines to maintain their finish. Stainless steel countertops should be cleaned along the grain to prevent surface scratching. LOC Scientific provides care and maintenance guidelines for all countertop materials supplied as part of project documentation.

Yes. LOC Scientific fabricates laboratory countertops to custom dimensions and can accommodate non-standard bench lengths, depths, cutouts for sinks, service fixtures, or equipment, and special edge profiles. Custom fabrication is a standard part of the LOC Scientific project process, and our team works directly with design drawings and field measurements to ensure precise fit. Lead times for custom countertops vary by material and project scope.

A drop-in laboratory sink is a separate fixture that is cut into the countertop and installed from above, with a visible rim resting on the countertop surface. An integral sink is molded or fabricated as part of the countertop itself, creating a seamless surface with no rim or joint that could trap contaminants or chemicals. Integral sinks are generally preferred in high-cleanliness or chemical-intensive environments because they eliminate joints where spills can accumulate. LOC Scientific supplies both drop-in and integral sink options and can recommend the appropriate configuration based on your lab's usage and cleaning requirements.

Laboratory countertop costs vary based on material, thickness, dimensions, edge profile, and whether cutouts or integral features are required. Epoxy resin countertops are generally priced in the mid-to-upper range, while phenolic resin offers a more affordable entry point with solid performance. Stainless steel countertops tend to carry the highest material cost. LOC Scientific provides itemized project quotes and can work within defined budget parameters to recommend the best material for your application and cost targets.

Epoxy resin countertops are the most commonly specified material for university science labs because they offer excellent chemical resistance, long-term durability, and low maintenance requirements in high-use teaching and research environments. Phenolic resin is also a popular and cost-effective option for teaching labs where chemical exposure is moderate. LOC Scientific has extensive experience outfitting university laboratory facilities and can guide material selection, layout, and product specifications to meet both institutional standards and budget requirements.

Yes. LOC Scientific specializes in custom laboratory casework and works directly with lab managers, architects, and facility planners to design cabinets and storage systems tailored to specific workflows, room dimensions, and equipment requirements. Customization options include non-standard dimensions, specialized interior fittings, integrated sinks or fixtures, and material combinations chosen for a lab's specific chemical environment. Custom casework is a core part of LOC Scientific's laboratory furniture offering.

Well-manufactured laboratory cabinets typically last 20 to 30 years with proper maintenance, though lifespan depends on the material, the intensity of daily use, and the chemicals present in the environment. Steel casework in moderate-use environments often reaches the higher end of that range, while casework exposed to harsh chemicals may require earlier replacement if not properly specified for those conditions. LOC Scientific uses professional-grade materials and hardware to maximize the service life of every casework installation.

A laboratory fume hood is a ventilated enclosure used to protect lab personnel from exposure to hazardous gases, vapors, and chemical fumes generated during experiments or processes. Air is drawn into the hood through the open front sash and exhausted through a duct system to the outside, preventing fumes from entering the lab environment. The face velocity of the incoming air, typically measured in feet per minute, is the primary metric used to assess fume hood containment performance. LOC Scientific supplies a full range of fume hood types to meet the specific hazard profiles and operational requirements of different laboratory settings.

A ducted fume hood is connected to a building's exhaust system and vents contaminated air directly outside the facility, making it the preferred choice for applications involving strong acids, bases, solvents, or toxic compounds. A ductless fume hood uses internal filtration, typically activated carbon, to remove chemical vapors before recirculating air back into the lab, making it suitable for lower-hazard applications where ductwork installation is not practical. Ducted fume hoods are generally considered the safer and more versatile option, as they are not limited by filter capacity or the range of chemicals they can handle. LOC Scientific carries both ducted and ductless fume hood configurations.

LOC Scientific offers a comprehensive range of laboratory fume hood types, including standard ducted fume hoods, ductless fume hoods, VAV (variable air volume) fume hoods, add-air fume hoods, perchloric acid fume hoods, radioisotope fume hoods, low-bench fume hoods, demonstration fume hoods, and ADA-compliant fume hoods for wheelchair operators. Each type is designed for specific applications, hazard levels, and facility requirements. Our team works with lab designers and safety officers to identify the appropriate hood type for each application and ensure the selected product meets applicable OSHA, ANSI/AIHA Z9.5, and SEFA standards.

A VAV, or variable air volume, fume hood automatically adjusts its exhaust airflow based on the position of the sash, reducing energy consumption when the sash is partially or fully closed while maintaining a constant face velocity at all sash positions. VAV fume hoods are recommended for facilities focused on energy efficiency and labs with high fume hood density, where the cumulative energy savings from variable airflow can be substantial. They integrate with the building's HVAC exhaust control system and are best specified during new construction or major renovation. LOC Scientific supplies VAV fume hoods and can coordinate with facility engineers on system compatibility and control requirements.

A perchloric acid fume hood is a specially designed enclosure built to safely handle perchloric acid, a highly reactive oxidizer that can form explosive perchlorates when it reacts with organic materials in the exhaust ductwork. These hoods are constructed from non-reactive materials such as stainless steel or PVC, and the ductwork includes a built-in wash-down system that regularly rinses interior surfaces to prevent perchlorate buildup. Standard fume hoods must never be used with perchloric acid, as the risk of explosion from residue accumulation is significant. LOC Scientific supplies perchloric acid fume hoods and can guide installation requirements and safety protocols for this specialized application.

ANSI/AIHA Z9.5 recommends that laboratory fume hoods be tested at least annually for face velocity and containment performance, and more frequently in high-use or high-hazard environments. Fume hoods should also be tested after any maintenance, repair, or modification to the hood or the building's HVAC system that could affect performance. All LOC Scientific fume hoods are factory-tested to the ASHRAE 110 standard before shipment, and our team can establish an ongoing testing schedule aligned with your facility's safety program and applicable regulatory requirements.

A fume hood is designed to protect lab personnel from chemical vapors and fumes by exhausting contaminated air out of the lab, but it does not provide protection from biological hazards or protect the sample inside the hood. A biosafety cabinet is designed to protect both the user and the sample from biological contaminants, using HEPA filtration and carefully controlled airflow patterns classified under biosafety level ratings from the CDC and NIH. Fume hoods are used for chemical work, while biosafety cabinets are required for work with biological agents. LOC Scientific can help you identify the correct containment equipment for your specific application.

Laboratory fume hood costs vary widely depending on the hood type, size, material construction, and whether specialized features such as VAV controls, wash-down systems, or perchloric acid compatibility are required. Standard ducted fume hoods are generally the most affordable, while specialized units such as perchloric acid hoods, VAV systems, and radioisotope hoods carry significantly higher price points due to their construction and control requirements. LOC Scientific provides project-specific pricing and can work with facility planners and procurement teams to identify solutions that meet both performance and budget requirements.

Laboratory service fixtures include a wide range of utility connections and safety equipment integrated into lab benches and casework, such as faucets, cup sinks, gas valves, vacuum connections, compressed air outlets, electrical outlets and switches, emergency eyewash stations, and emergency safety showers. These fixtures are specified based on the type of research being conducted and the utilities available in the facility. LOC Scientific's full line of service fixtures is built to SEFA standards and factory-tested, and our team can coordinate with mechanical and electrical contractors during facility planning and construction.

Laboratory faucets are engineered for the demands of scientific environments, including resistance to corrosive chemicals, compatibility with deionized or distilled water systems, and precise flow control for sensitive procedures. They meet ANSI/ASME standards and are available in materials such as polypropylene, stainless steel, and epoxy-coated metal to handle aggressive water chemistry and chemical splashes. Standard plumbing faucets are not designed for these conditions and can corrode, degrade, or contaminate the water supply in lab settings. LOC Scientific supplies laboratory-grade faucets in a range of configurations, including gooseneck, swing arm, and serrated tip styles, to meet different bench and sink applications.

OSHA's General Industry Standard 29 CFR 1910.151(c) requires that appropriate equipment for flushing or drenching of eyes and body be provided in the work area when someone is exposed to injurious corrosive materials. The ANSI Z358.1 standard provides more specific guidance, requiring eyewash stations to deliver a controlled flow of tepid water for a minimum of 15 minutes and to be reachable within 10 seconds from the hazard. LOC Scientific supplies ANSI Z358.1-compliant emergency eyewash stations and can help facility managers ensure their lab meets applicable safety requirements.

ANSI Z358.1 requires that emergency eyewash stations be located within 10 seconds of travel from the chemical hazard, which typically corresponds to a distance of approximately 55 feet or less on an unobstructed path. The path to the eyewash station must be free of barriers and should not require the user to pass through a door that could obstruct rapid access. In labs where highly corrosive materials such as strong acids or bases are used, positioning the eyewash station even closer to the hazard is strongly recommended. LOC Scientific can assist with eyewash station placement planning as part of a broader lab design or safety compliance review.

LOC Scientific supplies emergency eyewash stations, portable eyewash units, combination eyewash and face wash units, drench hoses, and emergency safety showers for laboratory environments. These products are available in plumbed and self-contained configurations to accommodate labs with varying access to a water supply. All safety station products supplied by LOC Scientific are designed to meet ANSI Z358.1 requirements. Our team can advise on product selection, placement, and installation requirements based on the specific hazards present in your facility.

Yes. LOC Scientific designs and installs laboratory benches and casework with service fixtures fully integrated into the build, including faucets, sinks, gas outlets, vacuum connections, electrical service, and safety equipment. Coordinating fixture placement during the casework design phase ensures proper utility routing, minimizes installation conflicts, and results in a clean, functional finished product. LOC Scientific works directly with mechanical, electrical, and plumbing contractors to ensure all service connections are properly coordinated during new construction and renovation projects.

Laboratory faucets are commonly manufactured from polypropylene, stainless steel, or epoxy-coated cast iron or brass, depending on the application. Polypropylene faucets offer excellent resistance to acids, bases, and corrosive chemicals and are widely used in labs working with aggressive reagents. For applications where water purity is critical, tin-lined, PVC, and polypropylene-lined faucets are available to prevent contamination of deionized or distilled water supplies. Stainless steel faucets are preferred in cleanroom and high-sterility applications. LOC Scientific carries multiple faucet materials and configurations and can recommend the appropriate option for your specific lab environment.

Yes. LOC Scientific supplies a full range of electrical service fixtures for laboratory benches and casework, including duplex and quad electrical outlets, ground fault circuit interrupter (GFCI) outlets for wet areas, and combination service panels that integrate electrical, gas, and other utility connections in a single unit. All electrical service fixtures supplied by LOC Scientific are designed for laboratory use and can be specified to meet UL listing requirements and applicable electrical codes. Our team works with electrical contractors and facility engineers to ensure proper specification and installation.

A laboratory bench is a fixed work surface, typically a long table with or without integrated storage, designed for general lab procedures. A laboratory workstation is a more complete, self-contained unit that integrates work surfaces, storage, utility connections, and often specialized features such as monitor mounts, equipment platforms, or ergonomic adjustability into a single cohesive configuration. Workstations are generally designed for a specific type of work or instrument, while benches provide a more flexible, general-purpose surface. LOC Scientific offers both standard laboratory benches and a wide range of specialized workstations, all manufactured in the USA, including the Millennium II, Dimension Next, Ergo Line, HD Modular, and Basics Modular.

Modular laboratory workstations can be reconfigured, expanded, or relocated as research programs evolve, making them a cost-effective long-term investment for labs that expect to change over time. They reduce the need for construction when layouts need to change and can be reused if a lab relocates or reorganizes. Fixed benches, by contrast, are more rigid but can be more economical for labs with stable, well-defined workflows that do not anticipate significant layout changes. LOC Scientific offers both modular and fixed bench systems and can help you evaluate which approach best fits your facility planning strategy.

Laboratory bench frames are typically constructed from powder-coated steel, stainless steel, or aluminum, chosen for their strength, chemical resistance, and ease of cleaning. Work surfaces are available in epoxy resin, phenolic resin, stainless steel, chemical-resistant laminate, and other materials selected based on the type of work being performed and the chemicals present in the environment. LOC Scientific offers bench frames and work surfaces in a range of material combinations and can assist in selecting the right pairing for your application and budget.

An ergonomic laboratory workstation is designed to support the health and comfort of lab personnel during extended work sessions, incorporating features such as height adjustability, monitor positioning, keyboard trays, and anti-fatigue surfaces. These workstations are particularly valuable for staff who spend long hours at a bench performing repetitive tasks, such as data entry, microscopy, or precision assembly. LOC Scientific's Millennium II workbench offers electric height adjustability and is specifically engineered for ergonomic performance in demanding lab environments, while the Ergo Line provides additional ergonomic configurations tailored to individual user requirements and institutional guidelines.

Yes, with the right bench system. LOC Scientific offers modular bench systems, including the Dimension Next and HD Modular, that can be reconfigured, extended, or reduced in size as research programs shift without requiring demolition or major construction. Modular systems use standardized components that can be combined in different configurations, making it straightforward to adapt a lab layout to new instruments, different team sizes, or changing workflows. For labs that anticipate frequent reconfiguration, specifying a modular system from the outset is the most cost-effective approach.

Load capacity requirements vary significantly based on the equipment being placed on the bench. Standard laboratory benches are typically rated for 500 to 750 pounds of uniformly distributed load, but heavy equipment such as centrifuges, analytical balances, large incubators, or instrument racks may require reinforced bench structures rated for significantly higher loads. LOC Scientific designs and supplies laboratory benches with load capacities matched to the equipment they will support, and can provide engineering specifications for custom or heavy-duty applications.

An electric wire harness workstation is a specialized laboratory bench designed for the assembly, testing, and quality control of electrical wiring harnesses and cable assemblies used in automotive, aerospace, defense, and industrial manufacturing applications. These workstations typically feature integrated wire routing boards, adjustable fixtures, organized cable management, and tool storage configured to support efficient harness assembly workflows. LOC Scientific's electric wire harness workstations are manufactured in the USA and designed to meet the specific ergonomic and functional requirements of wire harness production environments.

Standard laboratory bench height ranges from 30 to 36 inches depending on the task and user, with seated work typically at the lower end of that range and standing work toward the upper end. The correct height depends on the tasks being performed, the equipment in use, and whether the bench will be used sitting or standing. Microscopy, pipetting, and precision work may require specific heights to reduce fatigue and maintain accuracy. Height-adjustable benches such as the LOC Scientific Basics Modular, which adjusts from 30 to 36 inches in one-inch increments, and the Ergo Line range are the most flexible option when multiple users with different needs will share a workspace.

A fixed laboratory workstation is anchored to the floor or wall and provides a stable, permanent surface for work and equipment, typically offering higher weight capacity and more integrated utility connections. A mobile workstation is mounted on casters and can be moved within the lab or between rooms, offering flexibility for shared spaces, collaborative work, or temporary setups. Mobile workstations are popular in teaching labs, shared research spaces, and facilities that need to be reconfigured frequently. LOC Scientific offers both fixed and mobile workstation options and can configure mobile units with locking casters and storage for specific lab applications.

Laboratory seating is specifically designed to meet the demands of scientific work environments, including resistance to chemical splashes, easy cleaning and disinfection, compatibility with bench heights rather than standard desk heights, and construction materials that do not off-gas or harbor contaminants. Standard office chairs are not built for these conditions and can degrade quickly in lab environments, retain chemical residues, and pose contamination risks in sensitive settings. LOC Scientific supplies seating designed specifically for laboratory use across a range of categories, including laboratory, ESD and cleanroom, medical, industrial, and draft seating, with configurations to match different lab types and work styles.

Laboratory chairs and stools are commonly upholstered in vinyl, polyurethane, or ESD (electrostatic dissipative) materials, all of which can be wiped clean and resist chemical splashes. Frames are typically constructed from powder-coated steel or stainless steel for durability and corrosion resistance. Some lab seating is available with molded polypropylene seats for environments where upholstered surfaces are not appropriate. LOC Scientific supplies laboratory seating in a range of materials and can recommend the appropriate option based on the chemical environment, cleanliness requirements, and budget.

Quality laboratory seating is designed with chemical resistance in mind, with seat and back materials that can withstand exposure to common lab chemicals, cleaning agents, and disinfectants without cracking, staining, or degrading. Vinyl and polyurethane upholstery are the most common choices for chemical resistance in standard lab environments. For particularly aggressive chemical environments, molded polymer seating may offer better long-term durability. LOC Scientific can provide product specifications and chemical resistance information to help you select seating appropriate for your specific lab conditions.

Laboratory seating should include adjustable seat height to accommodate different bench heights and user sizes, lumbar back support to reduce fatigue during extended work periods, and a stable base appropriate for the flooring type. Footrests are important for stool users working at elevated bench heights, as they prevent leg fatigue and promote better posture. Adjustable armrests and forward seat tilt are additional features that reduce shoulder strain and maintain alignment for users performing repetitive bench tasks. LOC Scientific offers laboratory seating with a range of ergonomic adjustments, including anti-slip casters for hard floors and soft casters for carpeted surfaces, and can assist in selecting configurations that meet occupational health guidelines for your team.

A laboratory stool is a backless or short-backed seat mounted on a tall pedestal, designed for use at elevated lab bench heights and allowing users to stand or perch rather than sit fully. A laboratory chair has a full back and is configured for seated work at standard bench or desk heights, providing more support for prolonged sitting. Stools are more common at standing-height benches where users move frequently between sitting and standing positions, while chairs are preferred at lower work surfaces or for tasks requiring extended concentration. LOC Scientific offers both stools and chairs in a range of heights and configurations.

Yes. LOC Scientific offers laboratory seating designed for cleanroom and controlled environments, featuring smooth, non-porous surfaces with no exposed foam, minimal crevices, and materials compatible with isopropyl alcohol, bleach solutions, and other common cleanroom disinfectants. Cleanroom-rated seating is typically constructed with sealed upholstery or molded polymer seats and is ISO-classified for the cleanroom level it is intended to support. Please consult with our team to confirm the appropriate seating specification for your cleanroom classification and cleaning protocol.

Laboratory stools are typically available with seat heights ranging from approximately 18 to 29 inches for standard bench-height applications and 24 to 34 inches or higher for elevated bench and standing-height applications. Pneumatic height adjustment allows users to quickly set the seat to their preferred position, while fixed-height stools are a lower-cost option where height variability is not needed. LOC Scientific can recommend the appropriate height range based on your bench heights and the ergonomic needs of your team.

A dental lab workstation is a specialized work surface designed to support the specific tasks performed in dental laboratory environments, including casting, finishing, polishing, model trimming, and digital workflow processes.

Forensic laboratories have specialized design requirements that reflect the legal and scientific standards governing evidence handling and analysis. Key design considerations include controlled access and evidence chain-of-custody workflows, physical separation between evidence receiving, processing, and storage areas, high-durability and easy-to-clean surfaces throughout, appropriate ventilation for chemical and biological evidence processing, and durable casework and storage that can withstand heavy daily use. LOC Scientific provides full laboratory design services for forensic facilities and can assist with layout planning, product specification, and coordination with architects and construction teams.

Epoxy resin and stainless steel are the most commonly recommended countertop materials for forensic labs because of their non-porous surfaces, chemical resistance, and ease of decontamination. Non-porous surfaces are critical in forensic settings to prevent cross-contamination of evidence and to allow thorough cleaning between cases. Stainless steel is particularly preferred in autopsy and biological evidence areas, while epoxy resin is widely used in chemistry and trace evidence analysis spaces. LOC Scientific provides countertop recommendations based on the specific functions of each area within the forensic facility.

Forensic labs typically use standard ducted fume hoods for chemistry and toxicology work involving volatile organic compounds, solvents, and reagents. Fume chambers are also used in forensic environments for controlled processing of evidence items that require contained ventilation. In areas where perchloric acid is used in evidence processing, perchloric acid fume hoods with integrated wash-down systems are required. Radioisotope fume hoods may be needed in labs that handle radioactive evidence or conduct forensic radiation analysis. LOC Scientific supplies the full range of fume hood and fume chamber types needed for forensic applications and can help identify the appropriate unit for each functional area.

Forensic laboratories require furniture and casework that support strict evidence chain-of-custody protocols, including lockable storage for evidence, defined and separated workflow zones to prevent cross-contamination, and surfaces that can be thoroughly decontaminated between cases. The legal admissibility of forensic findings depends in part on the integrity of the evidence handling environment, which places higher demands on lab design and furniture specification than a typical research setting. LOC Scientific understands these requirements and designs forensic lab furniture that supports both operational efficiency and legal defensibility.
