Class 1 Microbiological Safety Cabinets

Class 1 operator protection microbiological safety cabinets from CAS, designed to the requirements of EN 12469:2000.

Class 1 microbiological safety cabinets provide operator protection by means of a constant air inflow through the open front working aperture, which prevents escape of airborne particulate contamination from the cabinet.
