Biosafety Cabinet is an encased laboratory unit that offers protection to the individual handling the unit, the sample being handled and the immediate surroundings from harmful pathogens and aerosol contaminants. The use of Biosafety Cabinet units in India is extensive in various applications including in pharmaceutical industries, microbiology laboratories, hospitals, biotechnology firms, research institutions, and diagnostic centers. In contrast to the laminar airflow cabinet, the biosafety cabinet uses filtered airflow for ensuring a sterile working area without exposing the user to any aerosols.
What Is a Biosafety Cabinet?
Biosafety Cabinet (BSC), otherwise referred to as biological safety cabinets or microbiological safety cabinets, are used for the manipulation of low- to moderate-risk biological agents. The most common Class 2 Biosafety Cabinet protects personnel, product, and the environment using a controlled flow of vertical air and high efficiency particulate air (HEPA) filtration.

Biosafety Cabinet Types
There exist three Class II Biosafety Cabinets each tailored to serve in certain laboratory situations. A2 Class II Biosafety Cabinet recycles about 70% of the HEPA filtered air from within the workbench while the other 30% is vented, hence making it suitable for various microbiological and pharmaceutical processes. B1 Class II Biosafety Cabinet vents 60-70% of the filtered air and recycles the remaining. Therefore,
it is ideal for certain types of research where small quantities of hazardous chemicals need to be used. B2 Class II Biosafety Cabinet has total exhaust without recycling any of the air within the workbench, thus making it preferable in laboratories with volatile toxic substances.
Real-World Application
An Indian pharmaceutical quality control lab enhanced its lab efficiency by replacing an existing laminar flow hood with a Class II biosafety cabinet during sample preparation in a sterile manner. This was made possible through better air circulation and filtration by means of HEPA filters.
Key Features
Biosafety Cabinet possesses a high level of technology that provides high standards of laboratory safety, performance, and ease of usage. This equipment has a 99.999% efficient HEPA filter that helps in removing airborne particles and microorganisms from the work environment making it completely sterile. Its digital controller based on microprocessors helps in the effective monitoring of the device as well as in its easy functioning.
Its low noise blower system makes its operation convenient for users during the process of laboratory experimentations. The equipment has a stainless steel work surface that ensures the high standards of strength, durability, and easy cleaning of the surface.
For providing high standards of sterility and visibility, Biosafety Cabinet is equipped with a fluorescent light and also a UV lamp that sterilizes the work space when the machine is not in operation. There is also an audio-visual sash alarm which alerts the user if the front sash is not placed properly.
