BBF SERIES – BENCHTOP BIOFLOW™ CHAMBER
The Class II, Type A2 Laminar Flow Biological Safety Cabinet provides protection for the user, product and the environment from particulate and aerosol hazards. The work area of the biological safety cabinet is continuously bathed with positive pressure ISO 5/Class 100 HEPA-filtered air to protect the product from contamination while an inward airflow protects the user. Hoods that are placed in a cleanroom must be constructed with materials that are highly durable, non-shedding and can withstand rigorous cleaning protocols. The front viewing panel allows for additional ambient light and visibility into the work area and has a unique, recessed, contoured shape, which creates an aerodynamic flow pattern and allows the operator to lean into the work area.

The BBF Series (Class II, Type A2) of Laminar Flow Biological Safety Cabinets are designed for the safe handling of cytotoxic agents and other hazardous drugs in Pharmacy and Oncology settings. These biosafety cabinets eliminate cross-contamination and the accidental release of carcinogenic aerosols and drugs to the outside environment. The laminar flow principle consists of moving individual streams of unidirectional, ultra-clean air along parallel lines with minimal turbulence. Approximately 70% of the air from each cycle is recirculated through the supply HEPA filter while the remaining air is discharged from the biological safety cabinet through the exhaust HEPA filter.

Operation as a Class II, Type A2 Biological Safety Cabinet
Our 3 and 4 foot units can also be converted into a Class II, Type A2 Biological Safety Cabinet as required by USP <800>. External exhaust system to vent (duct) the remaining HEPA filtered air to the outside is possible by ordering a thimble transition piece. The BBF Series of Vertical Laminar Flow Biosafety Cabinets passes the Biological Tracer Containment tests of the National Institutes of Health (NIH), the National Cancer Institute (NCI), and the National Sanitation Foundation (NSF).
