Biosafety cabinet (BSC) is a ventilated, enclosed workspace that provides protection for the user, the sample, and the environment when working with biohazardous or infectious agents. It uses a combination of HEPA filtration, laminar airflow, and containment to prevent exposure to pathogens and protect the product from contamination. BSCs are used in research, clinical, and production settings for tasks such as handling cell cultures, pathogens, and other sensitive biological materials.
