Tufts University Certification of Biological Safety Cabinets

Certification of Biological Safety Cabinets for Tufts University

Class II biological safety cabinets were invented in the 1970s for the purpose of protecting the agents in use, operator and the environment from aerosols of hazardous biological agents produced during experiment procedures and accidents involving hazardous agents inside the cabinet. In order to minimize microbial contamination by unwanted agents such as mold spores, the air within the cabinet is sterile, free particulates including all viruses, bacteria, mold spores and other potential airborne biological contaminants. Hence, as long as all equipment and materials brought into the cabinet are sterile, then there is no need for flaming to ensure aseptic culture conditions including subculture of agents, cell lines and tissues.
