Release time：
2025-02-27
In the daily work of biosafety laboratories, safety protection is crucial. As the most common protective barrier in laboratory biosafety, biosafety cabinets can effectively prevent the escape of aerosols containing hazardous or unknown biological particles, providing comprehensive protection for laboratory personnel, products, and the laboratory environment. This box type air purification micro negative pressure safety device is widely used in scientific research, teaching, clinical testing, and production in fields such as microbiology, biomedicine, genetic engineering, and biological products. It is an indispensable and important equipment in laboratories.
The Three Core Functions of Biosafety Cabinets
1. Personnel protection
Biosafety cabinets can prevent the overflow of contaminated aerosols in the workspace, create a safe operating environment for laboratory personnel, and ensure that they are protected from harmful biological particles during high-risk experiments.
2. Product protection
It can also prevent external unclean air from entering through the operating port, avoiding external pollution of experimental products, and keeping precision biological samples and high-value experimental materials pure under the protection of the safety cabinet.
3. Cross contamination control
The biosafety cabinet has super strong protective performance, which can effectively block cross contamination on both sides of the workspace, ensuring that experimental projects carried out simultaneously on both sides are independent and do not interfere with each other, laying a solid foundation for the accuracy and reliability of experimental results.
Classification and Application of Class II Biosafety Cabinets
Class II biosafety cabinets are the most common types in laboratories, with A2 and B2 being the most commonly used types.
A2 type biosafety cabinet
Suitable for low-risk experimental scenarios such as regular experiments, environmental testing, and food and drug testing. It can meet the needs of daily experiments while also efficiently utilizing laboratory space.
B2 type biosafety cabinet
It is not allowed to exhaust air in the room, which is more suitable for high-risk experiments such as oncology testing, chemotherapy experiments, and infectious disease experiments. This type of safety cabinet can filter harmful aerosols through high-efficiency air filters and directly discharge them outdoors, minimizing the risk of contamination in the laboratory.
Application fields of A2 and B2 biosafety cabinets
