Logic Class II, Type B2 Biosafety Cabinets (BSCs) provide comprehensive personnel, product and environmental protection from hazardous particulates, including agents requiring BSL 1-4 containment. Type B2 BSCs, sometimes referred to as 100% Exhaust or Total Exhaust BSCs maintain a minimum average airflow velocity of 100 feet per minute (fpm) through the sash opening and require a dedicated exhaust system and remote blower for each cabinet. All models are NSF-Listed, ensuring adherence to the highest safety standards.
Type B2 BSCs draw HEPA-filtered downflow air from the laboratory and exhaust all inflow and downflow air into the atmosphere after HEPA filtration. This design makes these cabinets suitable for work involving volatile chemicals as an adjunct to microbiological applications.
All contaminated air passes through the exhaust HEPA filter before being discharged from the laboratory via a dedicated exhaust system and remote blower. During operation, room air is drawn into the top of the cabinet and through a supply HEPA filter. This filtered air flows downward through the work area, while additional room air is drawn into the inlet grille at the work access opening. Because no air is recirculated, Type B2 BSCs provide robust safety for your critical operations.
