SafeFAST Elite class III ensures the total operator protection as they are suitable for work with the most hazard group 4 pathogens. Furthermore, they are conceived to offer the maximum protection to laboratory personnel, the community, and the environment because all hazardous materials are contained in a totally enclosed, ventilated cabinet, when correctly installed in proper BL3 or BL4 laboratory. Both the transfer hatch and working chamber volumes operate in negative pressure to the surrounding environment with the exhausted air being vented through a system of double H 14 HEPA/ULPA filters. Working chamber is bathed by Class ISO 3 laminar flow avoiding product cross-contamination. |
