Biological Safety Cabinet BMB-II-“Laminar-S”-1,2

Air flow scheme - Microbiological Safety Cabinet Class 2 (Biological Safety Cabinet Class 2)

 

Class II Type B2 Biosafety Cabinet ensures environment, product, and personal protection during lab procedures where the circulation of filtered air is restricted due to the existence of possible chemical fumes that are released during the process. Since the filter does not catch these chemical fumes, it can be of potential danger to the operator if they are re-circulated in the workspace. Therefore, Class II Type B2 Biosafety Cabinets are ducted to a blower that is located on the outside of the cabinet, for total exhaust.

ATTENTION! The cabinet must be connected to an individual active exhaust system with a flow rate of 1135-1205 m3/h. The room where the cabinet is installed must have a supply ventilation system with a flow rate of not less than 1000 m3/h.
