BBF (Benchtop Bioflow Chamber)
Type A Laminar Flow Biological Safety Cabinet
The Class II, Type A Laminar Flow Biological Safety Cabinet provides protection for the user, product and the environment from particulate and aerosol hazards. The work area 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. Approximately 70% of the air from each cycle is recirculated though the supply HEPA filter while the remaining air is discharged from the hood through the exhaust HEPA filter.

Germfree's Comprehensive Line of Biosafety Cabinets is highly trusted worldwide in the Hospital and Health-system Pharmacy.
The BBF Series (Class II, Type A) Laminar Flow Biological Safety Cabinet is designed for the safe handling of cytotoxic agents and other hazardous drugs in Laboratory, Pharmacy and Oncology settings. This biosafety chamber eliminates cross-contamination and the accidental release of pathogenic microorganisms or carcinogenic aerosols and drugs to the outside atmosphere. Other applications include handling materials such as pollen, powders, allergens, dust, pathogen-free animals and plants.
The work area is bathed with HEPA-filtered unidirectional (laminar) flow ISO 5/Class 100 air to protect the product and personnel. Further, the exhaust air is HEPA-filtered to protect the environment from particulate and aerosol hazards. This filter removes organisms and particulates 0.3 micron in size with an efficiency of 99.99%. It is even more efficient for larger and smaller particles. 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 hood through the exhaust HEPA filter. This model can also be converted into a Class II, Type A2 Biosafety Cabinet by adding an appropriate exhaust system to vent (duct) the remaining HEPA filtered air to the outside.
Germfree's Biological Safety Cabinets are constructed of all-welded stainless steel with a pharmaceutical grade finish.
The BBF Biological Safety Cabinet is constructed of quality all-welded stainless steel with a pharmaceutical grade finish. The fluorescent light housing is externally mounted to provide optimum lighting into the work area. 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. It is this combination that produces the protective barrier for the operator by containing hazardous materials within the chamber. The viewing panel is hinged so it can be easily opened for cleaning and placement of larger objects into the work area. The stainless steel work tray can also be removed.
All-welded stainless steel stands are available at a fixed sitting or standing work height. For further ergonomic considerations, adjustable stands are available with either manual or electric height adjustment. For additional information and available options for Germfree's Biological Safety Cabinets please refer to the unit specification sheet.
The BBF Series of Vertical Laminar Flow Biosafety Cabinets passed the Biological Tracer Containment tests of the National Institutes of Health (NIH), the National Cancer Institute (NCI), and the National Sanitation Foundation (NSF). All units are NRTL listed with MET Labs to comply with UL 1262.
