Labculture® Class II Type B2
Biological Safety Cabinet (Total Exhaust)

Maximum Protection against Microbiological Agents and Chemical Fumes

Labculture® Class II Type B2 Biological Safety Cabinet is incorporated with the all the latest design features of Esco's NSF-listed Labculture® Class II Type A2 biosafety cabinet. The Labculture® Class II Type B2 BSC are designed to provide maximum protection during experiments where recirculation of filtered air is prohibited, mostly due to the presence of chemical fumes emitted during the process.

Chemical fumes cannot be filtered, therefore can be harmful to the operator when recirculated in the laboratory. This is the reason why Class II Type B2 cabinets have to be ducted to an external blower for total exhaust. Similar in design to the Class II Type A2 BSC, Labculture® Class II Type B2 BSC is suitable for experiments involving work assigned to biosafety level 1, 2 and 3.
