A facility manager is told to “order new lab casework,” then opens a catalog with dozens of cabinet families. The hard part isn't choosing a door style. It's matching each room to the chemicals, moisture, cleaning process, contamination risk, and service-life target that the casework must handle.
This guide is for lab managers, facility teams, procurement groups, architects, contractors, and buyers planning a new build, renovation, or compliance refresh. The central rule is simple: casework is infrastructure, not a commodity cabinet. Use a lab-type matrix first, then compare materials and work surfaces.
Quick decision guide
- General-purpose and education labs: Start with painted steel.
- Healthcare, pharmaceutical, biotech, cleanroom, and vivarium areas: Start with stainless steel, especially where wash-down and sterilization are routine.
- Wet chemistry, analytical, humid, and corrosive work: Compare phenolic resin with stainless steel.
- Dry teaching, write-up, office-adjacent, and lower-risk spaces: Wood or plastic laminate may control first cost.
- Acid storage and highly corrosive storage: Review polypropylene options.
- Always specify the cabinet and work surface together.
Who Needs This Guide and Why It Matters Now
A contractor is waiting for a casework decision before rough-in. Procurement has found a lower-priced cabinet, while the architect's finish schedule says little about disinfectants, wash-downs, or sterilization. The person approving the purchase may never handle the chemicals used at the bench. If the selected surface fails at an exposed edge or joint, replacement disrupts the room and costs more than choosing a suitable material before ordering.
Lab casework material selection by lab type gives each project team a practical way to resolve that gap. A general R&D room, pharmaceutical processing area, university chemistry teaching lab, and vivarium face different combinations of chemical exposure, humidity, hygiene requirements, sterilization, and impact. A cabinet that works in a dry write-up area may be a poor choice beside a sink or in a room cleaned with repeated disinfectant cycles.
The historical SEFA classification system groups laboratory casework into material families, including metal under SEFA 8M, phenolic under SEFA 8PH, plastic laminate under SEFA 8PL, polypropylene under SEFA 8P, and wood under SEFA 8W. That shared vocabulary helps architects, buyers, contractors, and suppliers compare specifications during planning and submittal review. The history and material families of laboratory casework provides useful background.
Use a room-by-room decision
Before requesting a quote, list every room and answer these questions:
- What chemicals are used or stored? Include acids, bases, solvents, stains, disinfectants, and cleaning agents.
- How much water reaches the casework? Record sinks, wet processes, wash-downs, humidity, and spill exposure.
- How is the room cleaned or sterilized? Distinguish routine wipe-downs from repeated wet cleaning or sterilization.
- What must the casework support? Note heavy instruments, carts, samples, waste, shelving, and access requirements.
This process prevents new-build teams from specifying the most resistant material everywhere. It also helps renovation teams decide which existing banks can remain and which workstations need replacement. For broader project planning, review this guide to finding the right lab equipment and furniture.
The Four Drivers Behind Lab Casework Material Selection
A good specification begins with four drivers. Don't shortlist materials until the project team has scored each room against them.
Chemical exposure profile
Chemical exposure includes more than the reagent used at the bench. Cleaning chemicals, disinfectants, stains, waste containers, and accidental spills can reach cabinet faces, edges, joints, and hardware.
Phenolic resin and stainless steel are strong starting points for broad chemical exposure. Polypropylene belongs in the conversation for acid storage and highly corrosive environments. Painted steel can serve general-purpose labs, but aggressive chemicals or deep finish damage can change the risk. Wood and laminate need a dry, lower-risk setting because water and chemicals can reach joints or edge banding.
Use the SDS and EHS requirements for the actual chemical list. A general material label isn't enough to confirm compatibility with a specific reagent.
Moisture and humidity
Moisture is a daily operating condition in wet chemistry, analytical, aquatics, glass-wash, and wash-down spaces. It also appears in rooms that seem dry until a sink, hose, or cleaning cart changes the exposure pattern.
Independent guidance places phenolic resin and stainless steel at the front of the decision for persistently wet environments. It also warns that wood and laminate can fail at joints and edge banding when water enters the assembly. This guide to lab casework materials and applications explains that split between wet exposure and dry-use applications.
Sterilization method
Ask how the room is cleaned, not only whether it is called sterile. Teams may use disinfectant wipes, repeated wet cleaning, heat exposure, UV processes, or other room-specific methods. The casework must tolerate the actual cleaning products and contact pattern without creating rough, porous, or damaged areas.
Pharmaceutical, biotech, cleanroom, and vivarium spaces usually place a high value on smooth, non-porous, easy-to-clean materials. Stainless steel is often the default where sterilization, hygiene, and wash-down occur together. Phenolic can fit some demanding environments, but the final choice must follow the facility's cleaning protocol and EHS review.
Hygiene and contamination risk
Contamination risk affects seams, corners, handles, undersides, and storage access. A cabinet that performs well in a dry teaching room may be a poor fit where staff must clean every surface frequently.
Practical rule: If the cleaning regime is aggressive, frequent, or moisture-heavy, move the specification toward stainless steel or phenolic rather than treating a finish upgrade as a substitute for the right material family.
Also consider how much equipment and storage will sit on or inside the casework. Strength, impact risk, access, and future reconfiguration matter alongside chemical resistance. Pair the material review with the planned laboratory work surfaces because the top and cabinet must work as one system.
Comparing Steel, Stainless, Wood, Phenolic, and Polypropylene
The five main material families each solve a different problem. Painted steel is the broad-use workhorse. Stainless steel prioritizes hygiene, moisture resistance, and sterilization. Wood and plastic laminate support dry, lower-risk spaces. Phenolic resin handles wet and chemically demanding work. Polypropylene is a specialist choice for highly corrosive storage.
The table below is a screening tool, not a chemical compatibility approval. Confirm the exact reagent, concentration, temperature, contact time, and cleaning product before final selection.
Lab Casework Material Comparison
| Material | Chemical Resistance | Moisture Tolerance | Cleanability | Best-Fit Lab Profile | Notes |
|---|---|---|---|---|---|
| Painted steel | Good for general lab exposure, finish dependent | Good when the finish remains intact | Simple routine cleaning | General-purpose, education, R&D, and mixed-use labs | Strong and durable, but scratches or chips need attention |
| Stainless steel | Very high for demanding applications, grade and chemical dependent | Very high | Excellent for frequent cleaning and sterilization | Healthcare, pharmaceutical, biotech, cleanroom, and vivarium spaces | Higher first cost, strong long-term fit for hygiene and wash-down |
| Wood or plastic laminate | Finish dependent and best in lower-risk rooms | Limited compared with metal and phenolic | Good in dry areas | Dry teaching, write-up, office-adjacent, and budget-sensitive spaces | Water at joints and edge banding is the main concern |
| Phenolic resin | Broad chemical resistance | Very high | Very good for wet work and routine cleaning | Wet chemistry, analytical, histology, glass-wash, and humid spaces | Good balance of chemical and moisture performance |
| Polypropylene | Strong choice for highly corrosive storage | Very high | Good when specified for the storage application | Acid storage and highly corrosive environments | Use as a targeted solution, not a default for every room |
Painted steel
Painted steel fits rooms that need strength, durability, and practical cost control. It is commonly mapped to general-purpose and education labs, and it can serve mixed-use R&D spaces where the chemical profile is controlled.
Its weakness is the coating. A deep scratch, chip, or incompatible chemical can expose the metal below. Inspect high-contact areas, sink zones, and storage locations during maintenance. If the room has frequent wash-downs or aggressive disinfectants, compare stainless and phenolic before choosing painted steel.
Stainless steel
Stainless steel is the clear front-runner when cleanability, sterilization, humidity, and wash-down drive the specification. It is commonly selected for healthcare, pharmaceutical, biotech, cleanroom, and vivarium environments. Vivariums face a demanding combination of humidity, ammonia, disinfectants, and frequent cleaning, which makes stainless steel 316 a typical selection in that setting.
Stainless steel also carries the longest service-life benchmark in the provided planning guidance, at 25+ years, compared with 20+ years for painted steel and phenolic. The stainless steel casework category can help buyers compare configurations, but the facility team still needs to approve grade and chemical compatibility.
Wood, phenolic, and polypropylene
Wood or laminate can be sensible in dry teaching rooms, office-like write-up spaces, and lower-moisture general research areas. Published guidance places wood and laminate at roughly 15 to 20 years of service life, while phenolic is commonly described at 20+ years. This lab casework buying guide uses those benchmarks to show why a lower first cost doesn't always create the lower annual cost.
Phenolic is the stronger choice for persistent wet exposure, broad chemical contact, and humid rooms. Polypropylene is more specialized. Use it when the storage environment calls for high resistance to acids or highly corrosive materials, then coordinate containment, ventilation, and segregation requirements with EHS.
Matching Material to Lab Type and Work Surface
The fastest way to make a sound choice is to assign a default material to each room, then adjust it for actual chemical and cleaning demands. Don't select a cabinet body first and add a countertop later. A work surface can change the performance of the whole station.
The pairing table below gives a starting point. The final specification should follow the room's SDS review, EHS direction, local code, and the surface manufacturer's compatibility information.
Casework and Work Surface Pairings by Lab Type
| Lab Type | Recommended Casework | Recommended Work Surface | Key Reason |
|---|---|---|---|
| General R&D | Painted steel | Phenolic or another surface approved for the work | Balances durability, flexibility, and practical cost |
| University chemistry teaching | Painted steel | Phenolic resin | Handles repeated use and controlled chemical exposure |
| Wet chemistry and analytical | Phenolic resin or stainless steel | Phenolic resin or epoxy resin | Supports moisture and chemical resistance |
| Pharmaceutical and biotech | Stainless steel | Epoxy resin or another approved non-porous surface | Supports cleanability, hygiene, and sterilization |
| Cleanroom | Stainless steel or phenolic | Epoxy resin or phenolic, based on the cleaning regime | Limits moisture and contamination concerns |
| Clinical, pathology, and histology | Phenolic resin or stainless steel | Epoxy resin or phenolic | Addresses stains, moisture, cleaning, and workflow needs |
| Electronics and semiconductor | Phenolic resin where appropriate | Surface selected for non-conductive and ESD needs | Matches electrical and surface-control requirements |
| Dry teaching or write-up | Wood, laminate, or painted steel | Laminate or another dry-use surface | Controls first cost where moisture and chemical exposure are low |
Match the room, not the building
A pharmaceutical facility may need stainless steel in a processing or clean area and a different material in an office-adjacent write-up room. A university may use painted steel in chemistry teaching rooms and wood in dry support spaces. Mixed-material specifications often control cost without placing wet or sterile rooms at risk.
For environmental testing, select materials based on the actual sample and reagent profile. Use this environmental testing lab furniture category as a related planning reference, then verify the surface and cabinet compatibility with the lab's chemical inventory.
Treat the work surface as part of the casework
A buyer should never approve a cabinet body without reviewing the top, sink, backsplash, edge, joints, and service penetrations. Independent design guidance says the bench top should reflect staining, scratching, and burning risks. It also states that only non-combustible and non-reactive laminates should be used where flammable, corrosive, or reactive materials are stored or used. The university design guideline for laboratory surfaces and hazards supports that rule.
For a renovation, prioritize rooms with damaged edges, swollen joints, failed coatings, or work surfaces that no longer match current chemicals. For a cleanroom conversion, review the entire cleaning and contamination-control plan before preserving existing wood or laminate banks.
A Five-Step Checklist for Specifying Casework
Use this checklist before the cabinet schedule is fixed. Casework is infrastructure, so specify it against the room's workflow, contamination risk, cleaning regime, and utility demands rather than selecting a cabinet from a catalog.
1. Inventory chemicals, sterilants, and water exposure
Build a room-by-room exposure list. Record reagents, stains, solvents, disinfectants, sterilants, sinks, hoses, wash-down areas, humidity, and likely spill locations. Have the EHS team review the list and identify materials that need special storage, separation, or additional protection.
“General lab” is not a material specification. Two rooms with the same label may have very different chemical and cleaning demands. Record what contacts the casework, how often surfaces are cleaned, and where water or spills will reach cabinet edges and joints.
2. Rank sterility, impact, and load demands
Set the risk that controls the decision:
- Sterility: Use smooth, cleanable materials where contamination control drives the room.
- Impact: Favor steel where carts, equipment, or repeated student use will strike the cabinets.
- Load: Check the weight and footprint of benchtop instruments, glassware, and stored supplies.
- Access: Confirm drawer, door, shelf, and service requirements before finalizing the cabinet schedule.
A chemically resistant panel does not compensate for weak construction, poor access, or inadequate support. Review the complete cabinet assembly against daily use, not only the exposed surface.
3. Match the material family to the room
Use painted steel for broad-use and teaching spaces, stainless steel for hygiene-focused or wash-down rooms, phenolic for wet and chemically demanding areas, wood or laminate for dry, lower-risk support spaces, and polypropylene for targeted corrosive storage.
Compare the selected material against room size, throughput, storage capacity, maintenance access, and replacement constraints. A lower-cost option may suit a small facility with moderate use. A more resistant or higher-capacity system may justify its cost where downtime, cleaning intensity, or limited floor area creates greater operating risk. The useful comparison is first cost and footprint versus flexibility, capacity, maintenance, and service life.
4. Pair the cabinet with the work surface
Approve the cabinet, top, edge treatment, joints, backsplash, sink, fittings, and utility openings as one assembly. Confirm chemical compatibility and cleaning instructions for every connected component.
For renovation projects, field-measure walls, floors, utilities, doors, and access routes before ordering. Existing conditions can alter cabinet depth, sink location, filler requirements, delivery access, and installation sequence.
5. Model total cost of ownership
List purchase, installation, maintenance, facility modifications, replacement requirements, and downtime risk. Use the service-life comparison from the earlier material review rather than copying the benchmark table into the specification.
For a 10-bench run, calculate annual cost per bench by dividing purchase, installation, and five-year maintenance costs by the expected service life, then by 10 benches. Run the calculation for each suitable material. This exposes whether a lower first cost remains favorable after maintenance and replacement planning.
Renovation note: Measure the existing room before finalizing the cabinet schedule. Early field verification supports smoother procurement, fewer layout changes, and better installation planning.

Standards, Planning Lead Time, and Working With Labs USA
A standards-based, lab-type-first process gives the project team a defensible reason for every material choice. Start with the applicable SEFA casework family, then coordinate structural performance, accessibility, work surface compatibility, storage, utilities, and installation details. The design team should also review relevant ANSI/BIFMA requirements and ADA reach considerations where they apply.
Don't approve a generic cabinet schedule and hope the finish will solve the problem. The material affects shop drawings, work surface details, sink integration, service penetrations, cleaning instructions, and final submittals. Procurement should ask for the product data, warranty limits, material details, and compatibility guidance before issuing a purchase order.
Labs USA provides casework, work surfaces, laboratory furniture, layout support, specifications, estimates, and installation coordination as one purchasing option. A buyer can request a room-by-room take-off, compare material families, and review a layout before finalizing the order.
Planning earlier can help the team coordinate utilities, confirm field conditions, reserve installation capacity, and reduce changes after drawings are approved. Waiting until rough-in is complete can limit material choices and create avoidable layout conflicts, especially when a project has several lab types in one facility.
Frequently Asked Questions About Casework by Lab Type
Can phenolic casework replace stainless steel in a cleanroom?
Sometimes, but not automatically. Phenolic may fit a cleanroom when its chemical, moisture, cleaning, and contamination performance meets the facility requirements. Stainless steel remains the safer starting point for repeated wash-down and sterilization. Confirm the decision with the cleanroom and EHS teams.
Which material suits an autoclave-focused room?
Start with stainless steel when heat, moisture, sterilization, and cleanability dominate. Review the full cleaning process, nearby work surface, joints, and equipment clearances before approval.
Can one lab use more than one casework material?
Yes. Use painted steel in general work areas, phenolic in wet zones, stainless steel in high-hygiene rooms, and wood or laminate in dry write-up spaces when the room conditions support it.
Does SEFA affect the material choice?
Yes. SEFA organizes casework into material families and provides a useful framework for comparing construction and intended use. It doesn't replace chemical compatibility or EHS review.
Should a renovation replace every cabinet bank?
Not always. Replace banks with moisture damage, failed finishes, poor chemical compatibility, or an unsuitable cleaning profile. Keep sound casework only after checking its material, dimensions, utilities, and future workflow.
How should buyers compare total cost?
Add purchase, installation, maintenance, facility changes, replacement needs, and downtime. Divide that total by expected service life instead of comparing sticker prices alone.
How can a buyer avoid installation problems?
Complete field measurements, confirm utility locations, coordinate sinks and surfaces, and approve shop drawings before fabrication. A layout planning call can expose conflicts before they reach the job site.
