Measurements in a laminar flow cabinet
In order to protect products and samples at microbiological laminar flow cabinets from contamination, and to shield staff and the environment from potentially hazardous material, ventilation is essential. A laminar flow cabinet has an opening through which the user can carry out work procedures inside the cabinet. It is constructed such that the user is protected, the risk of a product and a cross-contamination is low, and the escape of suspended airborne contamination present in the cabinet is controlled by suitably filtered convection air and by filtration of the air output. Accordingly, DIN EN 12469 demands the testing of the ventilation conditions and the air volume flow.
