Class II Type A2

The Class II, Type A2 Laminar Flow Biological Safety Cabinet provides protection for the user, product and the environment from particulate and aerosol hazards. These biosafety cabinets eliminate cross-contamination and the accidental release of pathogenic microorganisms or carcinogenic aerosols and drugs to the outside atmosphere. Other applications for these biological safety cabinets include handling materials such as pollen, powders, allergens, dust, and plants.

Our Biological Safety Cabinets are available with all-welded stainless steel stands for operation at a fixed sitting or standing work height. Our 3, 4, and 6-foot units can also be converted into a Class II, Type A2 Biological Safety Cabinet. External exhaust system to vent (duct) the remaining HEPA filtered air to the outside is possible by ordering a thimble transition piece.
