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.
hinged front sash made of laminated safety glass; opening, closing and upholding is carried out by gas springs;
side windows made of tempered glass;
slanted front surface of the cabinet;
work chamber lighting;
two electric sockets in the work chamber (in the right part of the rear wall);
airflow laminarization screen made of polymer micromesh;
three-section tabletop made of mirror stainless steel (AISI 304);
pullout (when inoperative, is stored outside the work chamber under the tabletop);
metal grille protecting the UV lamp;
dampers against any impact upon lowering the work opening screen.
Supply and Exhaust Air Filtration System:
two-stage filtration of the air coming into the work chamber: prefilter G4 and supply HEPA filter H14 located over the work chamber;
exhaust air coming out of the cabinet is cleaned by exhaust HEPA filter H14 located under the work chamber base;
removable exhaust hood for connecting the cabinet to the active exhaust system; the exhaust hood is equipped with joint clearance that prevents any impact of the exhaust system on the cabinet’s operation.
