Class IIB BSC

Metisafe® Class II type B2 Biological Safety Cabinets works under principles with full exhaust of Pre/HEPA filtered fresh air to outer athmosphere without recirculation. Exhausting through HEPA f ilter protects also environment. Those Airflow principles of Class II type B2 cabinets provide safe work with biological risk level 2+/3 agents and also with cytotoxic gas & materials. The room air is pulled in through the perforations located at front of the work plate and directed to blower plenum (inflow air). This airflow direction prevents reaching dirty air to materials over the working plate. Pre/HEPA filtered air supplied through top of the cabinet provides the work area protecting the work zone under ISO-5 class laminar airflow. Total air in the working cabinet fully exhausted without recirculation through exhaust blower fan to athmosphere by keeping working area under negative air pressure. In addition to primary air barrier accomplished by negative pressure within the working zone double wall negative plenum design of the Metisafe cabinet prevents particle escape to surroundings and zero leakage is ensured.
