Product Description

Biological safety Cabinet

PSI 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 down flow.
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 down flow.

PSI Class II Type B2 Biological Safety Cabinets

PSI Class II Type B2 cabinet all inflow and down flow air is exhausted after HEPA filtration to the external environment without re-circulation within the cabinet. Type B2 cabinets are suitable for work with toxic chemicals employed as an adjunct to microbiological processes under all circumstances since no re-circulation occurs. In theory, Type B2 cabinets may be considered to be the safest of all Class II biological safety cabinets since the total exhaust feature acts as a fail-safe in the event that the down flow and / or exhaust HEPA filtration systems cease to function normally. However, Class II Type B2 cabinets are, in practice,difficult to install, balance and maintain.
