For Chemical Laboratories Seamless Welding Class II A2 Biosafety Cabinets
Class II A2 Biosafety Cabinets Advantage:
1. Electric front window.
2. Time retention function.
3. HEPA filter life and UV life indicator.
4. Automatic wind speed with filter is adjustable.
5. The negative pressure around the working area can ensure the maximum safety of the working area.
6. Audiovisual alarm (replacement of filter, window height, abnormal air flow rate, etc.).
7. Most accessories are standard. No need to pay more, save money.
8. Remote control. It can be used to realize all functions, making the operation easier and more convenient.
9. Foot switch. During the experiment, adjust the height of the front window with your feet to avoid turbulence caused by arm movement.
10. Interlocking function: ultraviolet lamp and front window; ultraviolet lamp and blower, fluorescent lamp; blower and front window.

Biological safety cabinet (BSC) is a box-type air purification negative pressure safety device that can prevent certain dangerous or unknown biological particles from dissipating aerosols during the experimental operation. It is widely used in scientific research, teaching, clinical testing and production in the fields of microbiology, biomedicine, genetic engineering, and biological products. It is the most basic safety protection equipment in the first-level protective barrier of laboratory biosafety.
The working principle of Class II A2 Biosafety Cabinets :
The working principle of the biological safety cabinet is mainly to suck the air inside the cabinet to maintain a negative pressure in the cabinet, and protect the staff through the vertical airflow; the outside air is filtered by a high-efficiency particulate air filter (HEPA) After filtering, enter the safety cabinet to avoid contamination of the processed samples; the air in the cabinet also needs to be filtered by a HEPA filter before being discharged into the atmosphere to protect the environment.
Classification of Class II A2 Biosafety Cabinets :
According to the NSF49 standard, the medium of biosafety level 1 (P1) refers to ordinary harmless bacteria, viruses and other microorganisms; the medium of biosafety level 2 (P2) refers to general pathogenic bacteria, viruses and other microorganisms; biosafety The medium of level 3 (P3) refers to microorganisms such as potent/fatal bacteria and viruses, but can be cured after infection; the medium of biosafety level 4 (P4) refers to microorganisms such as potent/fatal bacteria, viruses, etc., and it is not easy to cure after infection . This standard divides biological safety cabinets into levels I, II, and III, which can be applied to the operation of media with different levels of biological safety.
