class 100 Class II Type B1 Biological Safety Cabinets
The Class II Type B1 biological safety cabinet has a common plenum from which 70% of air is exhausted, and 30% re-circulated to the work area as the downflow.
Type B1 cabinets also have a dedicated exhaust feature that eliminates re-circulation when work is performed towards the back within the interior of the cabinet. Toxic chemicals employed as an adjunct to microbiological processes should only be employed if they do not interfere with work when re-circulated in the downflow.
Biological Safety Cabinets, enclosed containers and other engineering controls are designed to remove hazardous biological materials. The biological safety cabinet is the principal device used to provide containment of infectious splashes or aerosols generated by many microbiological procedures.
The equipment is widely applicable and is used in biomedicine, microbiology and gene recombination. Our Biological Safety Cabinets have the following technical specification:
