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 operating of such specimen will make the use of these cabinets successful.
