Forensic Crime Lab Furniture Utah: Room-by-Room Guide
A forensic crime lab is not one lab. It is a set of rooms that each handle a different kind of evidence. Evidence comes in at a secure counter. DNA work needs clean rooms that stay apart from each other. Toxicology needs chemical benches and hoods. Firearms needs heavy benches. All of it has to protect the chain of custody.
This guide is for lab managers, facility teams, buyers, architects and contractors who are planning forensic crime lab furniture in Utah. It explains what each section of a crime lab needs, which surfaces fit which rooms, how to size benches, and how to get an accurate quote.
Quick answer
- Plan the furniture room by room. Intake, DNA, trace, toxicology, firearms and evidence storage all need different benches, surfaces and storage.
- Pick the surface by the hazard: epoxy resin near fume hoods, stainless steel where biological evidence touches the top, laminated maple for firearms and vehicle benches.
- Keep pre-PCR and post-PCR DNA work in separate rooms with one-way movement.
- Give every analyst a locking cabinet for in-process evidence.
- Lay out the evidence route first, then place the benches. Our free lab layout configurator is a good place to start.
Why Forensic Lab Furniture Needs Its Own Plan
Most furniture problems in a crime lab show up during coordination, not on the first drawing. A bench fits the floor plan but sits in the path of evidence traffic. A shared cabinet forces DNA staff to walk through a clean room. A fume hood ends up as chemical storage. Each of these mistakes can slow casework, add contamination risk, or weaken the chain of custody.
Utah shows how much these labs have grown. The Utah Bureau of Forensic Services has been accredited since 1996. It runs three labs: the central lab in the Salt Lake area, a northern lab in Ogden, and a southern lab in Cedar City that opened in 2021. The central lab moved into the new Unified State Laboratory in Taylorsville in 2017. News coverage at the time put that building at about $41 million and 90,000 square feet, with chemistry, trace, DNA and robotics space, a firing range and vehicle processing bays under one roof. The Utah Department of Public Safety calls the bureau the only full-service accredited forensic laboratory in Utah.
City and county agencies, medical examiners, university programs and private labs in Utah have the same needs on a smaller scale. For the wider public-sector picture, see our page on government and federal lab furniture and our guide to public health and forensic lab casework in Utah.
What Each Forensic Lab Section Needs
The best planning source we have found is the NIST forensic laboratory facility handbook (NIST IR 7941). Its Appendix B lists design ideas for each section of a crime lab. The table below sums up the furniture items it names. Treat them as a starting point that your users, architect and accrediting body will adjust.
| Lab section | Furniture the NIST handbook lists | Surface to look at | Start planning with |
|---|---|---|---|
| Evidence receiving | Transaction counter with clerks on the secure side, forms counter, packaging bench, after-hours pass-through drop-off lockers | Durable, easy-to-clean top | Lab bench configurator |
| Forensic biology and DNA | U-shaped analyst bench, secure in-process evidence cabinet, exam rooms with mobile tables, separate pre- and post-amplification rooms, 3 ft deep benches for sequencers and robotics | Stainless steel where biological evidence is placed | Stainless steel casework |
| Trace and latent prints | Analyst bench, fume hood or exhaust snorkel, microscope benches, dusting stations, superglue fuming cabinets with their own exhaust | Epoxy resin near hoods, chemical-resistant laminate elsewhere | Exhaust snorkel configurator |
| Toxicology and controlled substances | Analyst bench, 36 in deep instrument benches with rear access, reagent prep bench, fume hood with chemical storage base cabinets, ventilated base cabinets for instrument pumps | Epoxy resin in hood and chemistry areas | Fume hood configurator |
| Firearms and toolmarks | Analyst bench, map drawer base cabinets for bullet standards, weapon layout bench, heavy-load shelving for ammunition, high-density mobile storage for reference guns | 1.5 in laminated maple on armorer and machine room benches | Lab tables in Utah |
| Digital forensics | U-shaped workstation per analyst, secure evidence cabinet, heavy-duty shelving for bulky computer parts | Chemical-resistant or standard laminate | Workstations and tables |
Evidence intake and accessioning
Intake is where custody starts. The NIST handbook describes a transaction counter where officers stand on one side and evidence clerks work on the secure side. It adds a forms counter, a packaging bench and pass-through lockers so officers can drop evidence after hours without entering the secure area. Keep public, courier and lab traffic apart, and give clerks enough counter space to log and label each item.
DNA and forensic biology
DNA work depends on keeping rooms apart more than on any single product. UK forensic guidance says staff should not move between pre-PCR and post-PCR areas, and it describes passing items from pre-PCR to post-PCR through a hatch. Read the contamination-control guidance with your DNA technical leader. The NIST handbook points the same way. It calls for one-way flow, a ventilated and interlocked pass-through from pre- to post-amplification rooms, and stainless steel tops where biologically contaminated evidence is placed.
Each DNA room should have its own supplies, refrigerator and cleaning tools so nothing has to cross over. If you are comparing enclosures, read PCR hood vs biosafety cabinet and see our biosafety cabinets. Our page on PCR lab casework in Utah covers the same zoning for clinical labs.
Trace evidence and latent prints
Trace analysts need stable benches, good task lighting, microscope stations and local exhaust. Latent print sections add dusting stations and superglue (cyanoacrylate) fuming cabinets with their own exhaust. Wet evidence, like bloody clothing, needs a drying cabinet or room so it can dry without cross-contamination. Our guide to evidence drying and storage cabinets for Utah labs covers drying methods, sizing and layout.
Labs USA carries the TopAir Systems forensic line, which includes evidence drying hoods, fuming chambers, downflow workstations and ductless fume hoods. Plan the floor space, power and exhaust for these units at the same time as the casework around them.
Toxicology and controlled substances
Toxicology and drug chemistry rooms are chemistry labs with a custody layer on top. NIST lists 36 in deep benches for each instrument, room behind the instruments for service, ventilated base cabinets for vacuum pumps, and a fume hood with chemical storage base cabinets in the reagent prep area. Use epoxy resin tops where solvents and hoods are present.
Drug evidence and standards need locked storage. NIST describes separate evidence and standards rooms with full-height walls for the controlled substances section. Inside the lab, look at narcotic and controlled substance cabinets and read our guide to controlled substance storage for laboratories. Your security plan and DEA registration rules decide the final hardware.
Firearms and toolmarks
Firearms benches take heavy, repeated loads from vises, tools and weapons. This is the one place the NIST handbook calls for wood: 1.5 in thick laminated maple on the armorer’s bench, the machine room bench and the vehicle processing bench. Add map drawer cabinets for bullet standards, a weapon layout bench and shelving rated for heavy ammunition loads.
Choosing Casework and Work Surfaces
A crime lab almost always uses more than one material. NIST says steel or wood cabinets are preferred and plastic laminate is acceptable, and it recommends using mobile, flexible casework where it can. The work surface is where the hazard decides the choice.
| Material | Best fit in a crime lab | Watch out for |
|---|---|---|
| Painted steel casework | Most lab rooms, analyst benches, in-process evidence cabinets | Confirm the finish against the chemicals and cleaners you use |
| Stainless steel casework and tops | DNA, serology, evidence exam rooms, wet areas | Higher cost, and some chemicals can still stain or pit it |
| Epoxy resin tops | Toxicology, drug chemistry, reagent prep, next to fume hoods | Heavy, so check cabinet support and delivery routes |
| Phenolic resin tops | General lab benches that need chemical and moisture resistance at lower weight | Check heat and acid exposure before using it at a hood |
| Laminated maple tops | Firearms, toolmark machine room, vehicle processing benches | Not for wet, chemical or biological work |
| Chemical-resistant laminate | Lower-risk lab rooms that NIST does not assign to another top | Not for hood areas or biological evidence |
| Wood casework | Offices, case review rooms and some dry lab spaces | Keep it out of wet decontamination areas |
For a side-by-side look at the top two lab surfaces, read epoxy resin vs phenolic countertops. You can price tops in the lab countertop configurator and browse laboratory casework by material. For standards, the SEFA laboratory furniture resources cover metal casework (the SEFA 8 series) and work surfaces (SEFA 3). Ask any supplier which SEFA tests their products meet.

Evidence Storage That Protects Custody
Storage in a crime lab works at three levels. Plan all three before you size the benches.
- In-process storage at the bench. NIST calls for a secure evidence cabinet at each analyst’s workspace in almost every section. Items stay locked at the bench between steps instead of going back to the vault.
- Section evidence rooms. Many sections get their own evidence storage room with full-height walls secured to the structure above.
- Long-term and bulk storage. NIST suggests high-density mobile storage to save floor space, and it notes these systems need a high-strength floor structure.
Biological evidence often needs cold storage. NIST lists secured refrigerators, walk-in coolers and freezers, and temperature monitoring for DNA and toxicology evidence. Place cold storage close to the section that uses it so items do not travel through other work areas.
Utah sits in an active seismic region, so tall shelving and cabinets should be anchored. See our page on seismic lab shelving and storage restraint in Utah, browse laboratory shelving systems, and confirm anchoring details with your structural engineer.
Sizing and Layout for Utah Crime Labs
Good sizing starts with real numbers per analyst, not a generic room size. The NIST handbook gives these planning figures:
- Analyst bench: 15 linear feet of bench, or a 90 square foot U-shaped bench, per analyst in most lab sections. Firearms uses 20 linear feet when a comparison microscope is part of the bench.
- Extra bench: about 6 linear feet per analyst for a hood, sink or equipment.
- Instrument benches: 36 in deep, with access to the back of each instrument.
- Exam rooms: at least two. A large room with one 5 ft by 10 ft mobile table (or two 5 ft by 5 ft tables), and a small room with one 3 ft by 6 ft table (or two 3 ft by 3 ft tables), with access on all sides.
- Microscopes: 4 linear feet per microscope, or 5 linear feet for a comparison microscope.
The older U.S. Department of Justice forensic laboratory handbook sets a minimum of 150 square feet for each evidence examination room, with at least two rooms to keep victim and suspect evidence apart. Use these figures to check a plan, then adjust them for your staff count, caseload and instruments.
How to plan a forensic lab furniture layout
- Name each room’s purpose. Give every room one main job, such as intake, DNA extraction, amplification, toxicology or trace. This limits crossover between processes.
- Draw the evidence route. Mark where evidence enters, waits, gets examined, gets repackaged and leaves. Make it one-way wherever you can.
- Place fixed equipment first. Locate hoods, biosafety cabinets, sinks, refrigerators, instruments and pass-throughs before benches and shelving.
- Size benches per analyst. Apply the per-analyst bench figures above and add in-process evidence cabinets at each station.
- Check access and service. Test door swings, aisles, delivery paths and the space behind instruments. Plan for heavy items like epoxy tops and mobile shelving carriages.
- Review with users. Have analysts, evidence staff, safety staff, facilities, the architect and the installer mark up the plan before you approve it.
Build the first draft in the lab layout configurator. Then detail each run in the base cabinet configurator and wall cabinet configurator. All of our free laboratory design tools are in one place.
Practical rule: If staff must cross a clean area to reach a shared cabinet, move the cabinet or change the layout.
Fume Hoods, Snorkels and Safety Review
Furniture follows the lab’s safety plan. It does not replace it. Review these points with your safety officer, mechanical engineer and the authority having jurisdiction.
- Hoods are not storage. SEFA 1 says materials should not be stored in a fume hood. Extra items hurt hood performance and shrink the work surface.
- Flammables under hoods. SEFA’s fume hood practices say flammable materials should never be stored below a hood in anything but an NFPA-specified, UL-listed or FM-approved solvent cabinet. See our laboratory safety cabinets and chemical storage cabinet requirements.
- Local exhaust. Snorkels work for small, local tasks where a full hood is too much. Plan the reach, mount point and duct route with the bench. Start with our exhaust snorkels.
- Ventilation by room. DNA, drying, fuming and chemistry rooms each have different air needs. Our forensic evidence lab ventilation guide covers them in more detail.
- Chemical fit. Confirm that tops, sinks, sealants, finishes and hardware hold up to the chemicals and cleaners on your list.
Browse laboratory fume hoods or size one in the fume hood configurator. A good quote lists its assumptions. It should not promise code compliance before the site, equipment list and local rules have been reviewed.
Installation, Lead Time and Local Support in Utah
Forensic projects mix standard parts with custom ones. Standard casework sizes and common tops are often easier to source. Stainless steel runs, custom evidence cabinets, specialty forensic equipment and mobile shelving usually take more planning. Lead times change by product and season, so ask for them in writing with the quote. Our guide to lab furniture lead times explains what drives them, and our quick ship lab furniture covers in-stock options.
Fast delivery only helps when the furniture fits the approved layout. Shipping casework before service locations, door sizes and floor conditions are confirmed often leads to costly field changes.
Questions to ask before you order
- Which items are standard, and which are custom built?
- Who checks field dimensions with the architect and contractor?
- Who handles receiving, staging and installation?
- Are the installers trained on the systems you selected?
- How are damaged, missing or wrong parts handled?
- What drawings and care documents come with turnover?

Common Forensic Lab Scenarios
| Your situation | Focus first on | Helpful tool |
|---|---|---|
| New forensic building | Room separation, evidence route, hood and utility locations, then casework | Lab layout configurator |
| Renovating an existing lab | Measure walls, doors, utilities and exhaust. Use mobile tables and storage to limit demolition | Lab bench configurator |
| Growing evidence volume | In-process cabinets, section evidence rooms, mobile storage and floor load | Shelving systems |
| Adding DNA capacity | Separate pre- and post-PCR rooms, stainless tops, pass-through, dedicated supplies | Stainless steel casework |
| Toxicology or drug chemistry | Deep instrument benches, epoxy tops, hoods, approved solvent storage, locked storage | Fume hood configurator |
| Shared forensic and public health building | Keep forensic and public health workflows in separate rooms where access rules differ | Utah lab furniture hub |
When you request pricing, send a marked-up plan and a room-by-room list. Include dimensions, materials, hardware, security features, utility points, delivery and install scope, and the equipment list. That lets the supplier catch conflicts before the quote is final.
Frequently Asked Questions
What surface is best for forensic evidence work?
It depends on the room. The NIST handbook suggests stainless steel where biologically contaminated evidence is placed, epoxy resin where fume hoods or chemical-rated biological hoods are installed, and laminated maple for firearms and vehicle benches. Check your choice against the chemicals and cleaners you use.
How much bench space does each forensic analyst need?
The NIST handbook plans for about 15 linear feet of bench, or a 90 square foot U-shaped bench, per analyst in most sections, plus about 6 linear feet for a hood, sink or equipment. Final sizes depend on your instruments, staff and caseload.
How big should an evidence examination room be?
The DOJ forensic lab handbook sets a minimum of 150 square feet for each evidence examination room. It calls for at least two rooms so victim and suspect evidence stay apart, with a mobile exam table that can be reached from all sides.
Can one bench support both DNA and trace work?
It is not a good idea. Shared benches raise contamination risk. Use separate rooms or clearly separated zones, and keep pre-PCR and post-PCR work in different rooms with one-way movement.
Should evidence storage be mobile or static?
Both have a place. Static shelving is simple and works well for heavy or bulky items. High-density mobile shelving fits more evidence in less floor space, but the floor must be able to carry the load and the aisles must work for staff and emergency exits.
Can a fume hood be used to store chemicals?
No. SEFA says materials should not be stored in a fume hood, and hoods should not stand in for an approved chemical storage cabinet. Keep chemicals in a cabinet chosen for the hazard.
What should a forensic lab furniture quote include?
Ask for room-by-room dimensions, materials, hardware, security features, utility coordination, delivery and install scope, lead time, warranty terms and any site assumptions. Send your floor plan and equipment list so the supplier can spot conflicts early.
When should furniture planning start?
Start in early design, before utilities and exhaust routes are fixed. Early review gives the team time to solve clearance, service access, storage and install problems before they affect construction.
