What is bio safety cabinets?
Bio safety cabinets, also known as biological safety cabinets (BSCs), are specialized laboratory equipment
designed to provide a sterile and controlled environment for working with hazardous biological materials.
They help protect the user, the environment, and the samples being handled from potential biohazards such
as infectious microorganisms, recombinant DNA, or other toxic biological agents.
There are three main classes of bio safety cabinets:
Class I: These cabinets provide product protection only, meaning they primarily safeguard the material
inside the cabinet from environmental contamination. They do not offer significant protection to the user
or the surrounding environment.
Class II: The most commonly used type, which comes in two subclasses:
Class II, Type A: Provide personnel, environmental, and product protection by drawing air through a HEPA
filter before it is exhausted or recirculated.
Class II, Type B: Offer enhanced protection over Type A, often including more air exchanges per minute,
and may include a built-in exhaust system to outside atmosphere.
Class III: Also known as glove boxes, these cabinets provide maximum protection by enclosing the workspace
completely. Air is filtered both when entering and leaving the cabinet, providing complete protection for the
operator and the environment. They are typically used for handling highly infectious agents that require the
highest level of containment
