Class III
Class III
A Class III Biological Safety Cabinet is designed for work involving Risk Group 4 microorganisms. Its gas-tight enclosure provides a high level of protection for both personnel and the surrounding environment from the materials being handled.
Class III biological safety cabinets are also known as glove boxes because operations are performed using long-sleeved gloves. These gloves are permanently attached to the cabinet front, completely isolating the operator and the external environment from the procedures carried out inside the chamber.
The cabinet is equipped with air filtration systems designed to provide maximum protection for personnel and the environment. Materials that need to be introduced into the chamber are transferred through a pass box. The pass box allows materials to be safely moved into and out of the working chamber while maintaining controlled separation from the surrounding area.
