Class 2 Biosafety Cabinets are designed to provide protection to the operator, environment, and materials inside the workspace. These Biosafety Cabinets are utilized for containing low-to-moderate-risk biohazardous materials. These Biosafety Cabinets have downward airflow and HEPA filters that re-circulate air providing the required level of protection from microorganisms and aerosols. As these Biosafety Cabinets are extensively used in drug preparation, chemotherapy preparation, clinical research, medical and pharmaceutical sectors, life science and industrial laboratories, etc. they must follow relevant application-specific standards.

Different Names Same Purpose
A Biosafety cabinet is called by several names in the research industry; microbiological safety cabinet, biological safety cabinet (Acronym: BSC), and Biosafety hood are such common names which are referred to by microbiologists.

Types of Class 2 Biosafety Cabinet

In order to meet varying research and clinical needs, Biosafety Cabinets are designed mostly in 3 types i.e. Type A2, Type B1, and Type B2. Regardless of type, each cabinet provides the same level of protection. According to international sanitation standards, there are exactly the same pass-and-fail criteria for all of them.

Now how do we differentiate each Class 2 Biosafety Cabinet? Each Biosafety Cabinet is differentiated by a number of factors some of them are the amount of air re-circulation, air ventilation, and negative and positive pressure. Before buying a cabinet a user must know the basic differences between these 3 types of Biosafety cabinets which are explained below:

Biosafety Cabinet Class 2 Type A2:
In this type of Class II BSC, approximately 70% of the HEPA-filtered air is circulated through the cabinet, while 30% passes through an exhaust HEPA filter and is discharged.

Biosafety Cabinet Class 2 Type B1:
This Class II BSC exhausts 60% - 70% of the HEPA-filtered air, while 30% - 40% air is re-circulated inside the workspace through a HEPA filter.

Biosafety Cabinet Class 2 Type B2:
It is a total exhaust type BSC, with no re-circulation inside the workspace; blower exhausts 100% of the filtered air.

Biosafety Cabinet Maintenance

In order to take optimum use of a Biosafety cabinet and maintain operational integrity, proper maintenance is essential. A Biosafety operator must follow routine cleaning and inspection schedule. As chemicals are extensively used in these Biosafety Cabinets, filter saturation should be checked regularly, and if need replace immediately. Other minor check-ups should be done on a regular basis such as air flow, surface cleaning, motor, lighting and electrical switches, etc.
