The Class II Laminar Flow Biological Safety Cabinet, or the Biosafety Cabinet, combines product, operator and environmental protection. It was developed to provide protection from diverse types of biohazardous material. The biosafety cabinet is similar to the conventional fume hood in providing protection for the operator. It differs from the conventional fume hood by also offering protection for the work in progress and the environment.
BIOLOGICAL SAFETY CABINETS
BBF (Benchtop Bioflow Chamber)
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 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 a HEPA filtered unidirectional (laminar) flow ISO 5/Class 100 air to protect the product and personnel and exhaust HEPA filtered air 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.
The BBF 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 please refer to the unit specification sheet.
The BBF Series of Vertical Laminar Flow Biological Safety 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.
BTE (benchtop biofume hood)
The BTE Series (Class II, Type B) Biological Safety Cabinet is designed for the safe handling of cytotoxic agents and other hazardous drugs in Laboratory, Pharmacy, and Oncology settings. This chamber eliminates cross-contamination and accidental release of pathogenic microorganisms or carcinogenic aerosols 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 a HEPA filtered unidirectional (laminar) flow ISO 5/Class 100 air to protect the product and exhaust HEPA filtered air 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%. The laminar flow principle consists of moving individual streams of unidirectional, ultra-clean air along parallel lines with minimal turbulence. This Class II, Type B2 cabinet is 100% exhausting and must be ducted (vented) to the outside of the building. There is absolutely no recirculation of air in the cabinet. This total exhaust feature makes the B2 hood suitable for not only handling particulates, but also fumes and gases.
