Biological Safety Cabinet Class III, The Class III Biosafety Cabinet is designed to work best with risk group 4 microorganisms. The gas-tight enclosure ensures the safety of the environment and the worker from the specimen that is being studied.The Class 3 Biological Safety Cabinets are also called Gloveboxes, due to work being conducted using arm-length gloves. These gloves are fixed to the cabinet glass which completely isolates the environment from the ongoing process inside the chamber. A Class III Microbiological Safety Cabinet provides a barrier between the specimen being examined and the user examining it. Prior planning and previous experience in the operation of such specimens will make the use of these cabinets successful

• The air inside the chamber passes the two HEPA filters before being discharged outside
• An independent exhaust system outside the work chamber is responsible for the airflow being maintained. It ensures that the pressure of the cabinet is negative
• Furthermore, the materials that need to be brought into the chamber are transferred through a pass box. The pass box is a feature of the BSC which ensures the safe movement of the materials from and into the working compartment. The pass box has two doors with electromechanical locks and with a penetrable pullout tabletop which makes it easier to move items into and out of the chamber
