1. What are Class II B2 Biological Safety Cabinets?
Class II B2 Biological Safety Cabinets are specialized laboratory enclosures designed to provide a high level of protection for operators, the environment, and products. They use a 100% exhaust system, filtering all air through HEPA filters before discharging it outside via hard-ducted ventilation. These designs ensures that no contaminated air is recirculated, making them ideal for use with hazardous chemicals and biohazardous agents.
2. How are Class II B2 Biological Safety Cabinet different from Class II A2 Biological Safety Cabinets?
While both Class II A2 and B2 cabinets provide protection for personnel, products, and the environment, the key difference lies in their airflow systems. Class II A2 cabinets recirculate 70% of filtered air into the work zone and exhaust 30% through HEPA filters. In contrast, Class II B2 cabinets exhaust 100% of filtered air externally with no internal recirculation. These makes B2 cabinets ideal for handling volatile chemicals requiring full exhaust.
