What is Class II Biosafety Cabinet?
Class II Biosafety Cabinet (BSC) is a ventilated containment device designed to provide both personnel and environmental protection from hazardous biological agents, while also maintaining product sterility. It operates by drawing air through a HEPA filter, creating a downward laminar airflow to safeguard the work area, and then filtering exhaust air to prevent contamination.
Five Types of Class II Biosafety Cabinets
Type A1
Similar to Type A2 but with lower inflow velocity (75 fpm). Mostly phased out in favor of Type A2 in modern labs.
01
Type A2
Recirculates 70% of the air back into the lab and exhausts 30% after HEPA filtration. Suitable for low-to-moderate risk agents (BSL-1, BSL-2).
02
Type B1
Maintains a higher level of containment, exhausting 70% of the air outside (hard-ducted) while recirculating 30%. Used for chemical vapors or toxic materials in addition to biological hazards.
03
Type B2
100% total exhaust (no recirculation), making it ideal for work with volatile chemicals and high-risk biological agents (BSL-2, BSL-3).
04
Type C1
A hybrid design allowing both recirculation (like Type A2) and full exhaust (like Type B2), providing flexibility for different applications.
05
How does the Class II Biosafety Cabinet work?
Here’s a simplified breakdown:
- Inflow: Air is drawn into the front grille, creating a barrier that prevents hazardous particles from escaping.
- Downward HEPA-filtered airflow: Clean, sterile air flows vertically from the top of the cabinet, shielding the work area from contamination.
- Exhaust: Contaminated air is either recirculated (after HEPA filtration) or safely expelled outside, depending on the BSC type.

Class II Biosafety Cabinet FAQs
Do all Class II BSCs require external exhaust systems?
No. Only Type B1/B2 cabinets require hard-ducting to exhaust air outside. Type A2/C1 recirculate filtered air back into the lab.
Are Class II BSCs safe for work with volatile chemicals?
Only Type B2 (100% exhaust) or Type C1 (in exhaust mode) are suitable for volatile chemicals. Type A2/B1 are not recommended due to air recirculation.
What is the lifespan of a Class II BSC?
With proper maintenance and filter replacements, Class II BSCs can last 10–15 years. HEPA filters typically require replacement every 3–5 years.
How do I choose the right Class II BSC type?
Type A2: General lab work (no volatile chemicals).
Type B1/B2: For toxic chemicals or higher-risk agents.
Type C1: Flexibility for mixed applications.
