The difference between B2 biosafety cabinet and A2 biosafety cabinet

First, let's take a look at the difference:
The difference between A2 type biosafety cabinet and B2 type biosafety cabinet
1、 Differences in Airflow Emissions:
1. The exhaust airflow of A2 type safety cabinet is efficiently filtered and then returned to the indoor area;
2. The exhaust airflow of B2 type safety cabinet is efficiently filtered and discharged outdoors.
2、 The usage of safety cabinets varies:
1. If there is a possibility of the experimental subject escaping radioactive gases or toxic irritants, please use a B2 type safety cabinet.
2. Otherwise, A2 type safety cabinet can be used.
3、 Difference in air exchange rate:
1. If using a B2 type safety cabinet, please ensure that the laboratory has sufficient ventilation, otherwise it will cause the suction wind speed of the safety cabinet to be too low, causing an alarm and seriously reducing its biological safety.
2. A2 is not required.
matters needing attention:
A biosafety cabinet usually refers to a secondary biosafety cabinet
The second level biosafety cabinet is divided into A2 and B2 types
A2 biosafety cabinet is used for conducting ordinary microbiological experiments, which can protect personnel, samples, and the environment. The operating space can achieve a hundred level purification level
The B2 biosafety cabinet is used for conducting experiments on samples with trace amounts of radioactivity and high infectivity. It can protect personnel, samples, and the environment. The operating space can achieve a hundred level purification level
Type applicable experiments
B2
Medical treatment: HIV (AIDS), PCR and tumor drug allocation laboratory
Pharmaceutical: Positive control room

A2 and B2 are applicable to laboratories outside of their designated locations.
