A biological safety cabinet (BSC), also called a biosafety cabinet, is a ventilated, enclosed laboratory workstation designed to protect the user, the sample, and the surrounding environment from exposure to biological hazards. BSCs use a combination of HEPA filtration and precisely controlled directional airflow to create a sterile work zone, making them standard equipment in microbiology, cell culture, pharmaceutical, clinical, and animal research laboratories.
Unlike a fume hood, which is designed to remove chemical vapors from the work area, a biological safety cabinet provides bidirectional protection: it filters air coming into the work zone to prevent sample contamination and filters exhaust air to prevent hazardous aerosols from escaping into the lab.
LabRepCo is an authorized distributor of biological safety cabinets from NuAire, Labconco, Flow Sciences, and Germfree. All models we carry meet NSF/ANSI 49 and EN 12469 certification standards.
Biological safety cabinets are classified by the level of protection they provide. Use the table below to identify which class is right for your application, then click through to browse products.
| Class | Personnel Protection | Product Protection | Typical Applications |
| Class I | Yes | No | Work with low-to-moderate risk agents; personnel and environment protection without product sterility |
| Class II | Yes | Yes | Cell culture, microbiology, BSL 1–3 work, pharmaceutical compounding, viral research |
| Class III (Glovebox) | Maximum | Maximum | BSL-4 work, high-risk pathogens, agents with no available vaccine or therapy |
LabRepCo carries a wide range of biosafety cabinets to cover every containment requirement. Browse by class below or contact our team for help selecting the right model.
| Category | Description | Browse |
| Class I Biological Safety Cabinets | Open-front cabinets providing personnel and environmental protection. Best for low-risk applications and procedures not requiring product sterility. | → View Class I BSCs |
| Class II Biological Safety Cabinets | The most widely used BSC type. HEPA-filtered downflow protects product and personnel simultaneously. Available in Types A2, B1, B2, and C1. | → View Class II BSCs |
| Class III Biosafety Cabinets & Gloveboxes | Gas-tight, totally enclosed cabinets providing maximum containment for BSL-4 agents and the most hazardous biological materials. | → View Class III BSCs |
| Custom Biological Safety Cabinets | Need a non-standard configuration? LabRepCo works with NuAire and other manufacturers to spec and build custom biosafety solutions for unique workflows. | → Request a Custom BSC Quote |
All biological safety cabinets sold by LabRepCo are tested and certified to the following standards:
LabRepCo’s team can advise on certification intervals, NSF-accredited field certifiers, and decontamination procedures.
A fume hood removes chemical fumes from the work zone but does not protect samples from contamination and does not filter exhaust air to protect the environment. A biological safety cabinet uses HEPA filtration to protect the user, the product, and the environment simultaneously, but is not designed for volatile chemicals unless a Type B2 (100% exhaust) model is used. Never use a laminar flow clean bench as a substitute for a biosafety cabinet when working with biological agents.
The class depends on your application. Class II Type A2 is the most common choice for general microbiology and cell culture. If your work involves volatile toxic chemicals in addition to biological agents, Class II Type B2 (total exhaust) is required. Class III gloveboxes are reserved for BSL-4 pathogens. Class I cabinets are appropriate when only personnel and environmental protection is needed and product sterility is not a concern. Contact LabRepCo for a free consultation — our specialists will help you select the right model.
NSF/ANSI 49 recommends annual field certification by an NSF-accredited certifier. Certification is also required after any relocation of the cabinet, filter change, major repair, or decontamination procedure. LabRepCo can connect you with accredited certifiers in your region.
LabRepCo carries biological safety cabinets from NuAire (LabGard series), Labconco (Purifier series), Flow Sciences, and Germfree. We are an authorized distributor for all brands we sell, ensuring full manufacturer warranty coverage and access to parts and service support.
