Biological safety cabinet (BSC) or a Biosafety Cabinet is a ventilated containment device found in laboratories around the world. BSCs are used in many applications, including cell culture, pharmaceutical, clinical and microbiological work. These work-spaces help protect the user and surrounding environment from pathogens. Engineered controls are built into the design of BSCs providing protection to the operator, product and environment. All exhaust air is HEPA filtered to remove hazardous agents such as viruses and bacteria. Many laboratories including clinical and research labs use biosafety cabinets.
