BTE (Benchtop Biofume Hood)

Type B Laminar Flow Biological Safety Cabinet

The Class II, Type B Laminar Flow Biological Safety Cabinet provides protection for the user and the product from particulate, gases/fumes and aerosol hazards. The work area is continuously bathed with positive pressure ISO 5/Class 100 HEPA-filtered air while creating a negative pressure airflow into the cabinet to provide user protection. All of the air entering the hood is ducted/vented to the outside of the building.

BTE Series (Class II, Type B) Biological Safety Cabinets

Germfree's BTE Biosafety Cabinets are 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 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. 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%. 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 Biological Safety Cabinet is a 100% Total Exhaust unit. The BTE must be ducted (vented) to the outside of the building as 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.

Germfree's Biological Safety Cabinets are constructed of all-welded stainless steel with a pharmaceutical grade finish.

The BTE Biological Safety Cabinets are 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 biosafety chamber. This also greatly enhances user comfort. 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 additional information and available options please refer to the unit specification sheet.

The BTE 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).
