Understanding laboratory classification is essential for anyone involved in laboratory design, whether you're planning a new facility, renovating an existing space, or sourcing lab furniture and equipment. Today, we'll walk through the most common types of laboratories found in the market, covering everything from dry and wet labs to specialized biosafety facilities - helping you identify which laboratory design classification best fits your research or production needs.
First, Dry Laboratory and Wet Laboratory
Dry laboratories refer to laboratories that do not use, or use minimal, water - such as precision instrument rooms, balance rooms, and high-temperature chambers. These spaces typically require stable environmental control (temperature, humidity, vibration, and dust) rather than plumbing infrastructure, which is an important consideration when selecting lab furniture and casework.
The wet laboratory refers to laboratories that need to be equipped with drainage for routine experiments such as sample processing, capacity analysis, centrifugation, sedimentation, and filtration. Wet labs generally demand corrosion-resistant countertops, proper ventilation, and reliable plumbing systems, so procurement teams should prioritize chemical-resistant materials when furnishing these spaces.
Second, Main Laboratory and Auxiliary Laboratory Design
1. The Main Laboratory
The main laboratory refers to the primary space for conducting core experiments such as analysis and research - for example, the precision instrument room.
2. Auxiliary Laboratory
Auxiliary laboratories support the core experiments carried out in the main laboratory, such as balance rooms, high-temperature chambers, and sample chambers. In practice, planning sufficient auxiliary space is often overlooked, but it directly affects workflow efficiency and sample integrity.
Third, Conventional Laboratories and Special Laboratories
1. Conventional Laboratory
Conventional laboratories are general chemical, biological, and physics laboratories with no pressure differential or purification requirements.
2. Special Laboratories
Special laboratories refer to facilities that meet specific needs, such as clean labs, antistatic laboratories, constant temperature and humidity laboratories, and mobile laboratories. This category also includes biosafety laboratories, radioactive laboratories, and laboratories for flammable and explosive dangerous goods - environments that pose potential risk to personnel or the surrounding environment and therefore require specialized design, containment, and ventilation systems.
Laboratory Classification by Discipline
Laboratories can also be classified by discipline into chemical laboratories, biological laboratories, and physical laboratories - a distinction that matters when choosing lab furniture, fume hoods, and safety systems tailored to each field.
First, The Chemical Laboratory
The chemical laboratory is mainly engaged in the research, analysis, and teaching of inorganic chemistry, organic chemistry, and polymer chemistry. It generally includes physical and chemical laboratories, precision instrument rooms, balance rooms, standard liquid rooms, medicine rooms, storage rooms, high-temperature rooms, and pure water rooms.
These spaces are primarily used for sample processing, capacity analysis, centrifugation, sedimentation, filtration, and other routine experiments, operations, or instrument analysis. For B2B buyers, chemical labs typically require acid- and solvent-resistant workbenches, dedicated fume hoods, and chemical storage cabinets that meet safety compliance standards.
Second, Biological Laboratory
Biological laboratories are divided into zoology laboratories, botany laboratories, and microbiology laboratories.
1. Zoology Laboratory
Toxicological experiments commonly used in zoology study the damage and mechanisms of chemical substances on biological organisms. This laboratory type serves as a testing and research site for toxicity identification, safety assessment, and functional mechanism studies, including standard animal experiment rooms. Clean animal laboratories are generally composed of a front area, rearing area, animal laboratory, and auxiliary area.
2. Botany Lab
3. Microbiology Laboratory
(1) Pathogenic Microbiology Laboratory
Laboratories handling pathogenic microorganisms are mainly focused on the identification and classification of viruses and bacteria. Facility design accounts for Biosafety Levels 1–4 depending on the pathogen involved, with higher levels presenting greater risk - including hazards to personnel, the environment, and the research subjects themselves. For this reason, pathogenic microbiology work should always be conducted in a purpose-built biosafety laboratory with appropriate containment, airflow control, and access management.
(2) Sanitary Microbiology Laboratory
Hygienic microbiology laboratories mainly focus on product testing and inspection, involving little to no biological hazard. These labs commonly test food, cosmetics, air, and water, with the primary concern being cross-contamination between samples. Sanitary microbiology work is typically carried out in a clean laboratory environment.
Third, The Physical Laboratory
The physical laboratory includes electrical laboratories, thermal laboratories, mechanics laboratories, optical laboratories, and comprehensive physics laboratories, among others.
How to Choose the Right Laboratory Type for Your Facility
Selecting the appropriate laboratory classification depends on several factors: the discipline of research (chemical, biological, or physical), the level of biosafety risk involved, drainage and ventilation requirements, and whether the space serves core experimentation or auxiliary functions. Industries such as pharmaceuticals, biotechnology, food and cosmetics testing, environmental monitoring, and academic research institutions each have distinct laboratory design needs.
When planning a new lab or upgrading an existing one, it's worth consulting with an experienced lab furniture and fit-out supplier early in the design process - this helps ensure compliance with safety standards, efficient workflow layout, and furniture that matches your specific lab classification (wet vs. dry, conventional vs. special).
Everything You Need to Know
Q1: What is the difference between a wet laboratory and a dry laboratory
A wet laboratory requires drainage for experiments like sample processing and filtration, while a dry laboratory uses little to no water and houses equipment like precision instruments and balances.
Q2: What are the main types of laboratories by discipline?
Laboratories are generally classified by discipline into chemical laboratories, biological laboratories (including zoology, botany, and microbiology), and physical laboratories.
Q3: What is a biosafety laboratory used for?
A biosafety laboratory is a specialized facility designed for handling pathogenic microorganisms, with containment levels (BSL 1–4) based on the hazard level to protect personnel, the environment, and research integrity.
Q4: What's the difference between a main laboratory and an auxiliary laboratory?
The main laboratory is used for core experiments and analysis, while auxiliary laboratories - such as balance rooms and sample chambers - support those core activities.
Q5: How do I choose the right laboratory classification for my facility?
Consider your research discipline, biosafety risk level, drainage/ventilation needs, and whether the space is for core or supporting functions; consulting a lab design specialist can help match the classification to your workflow.
