Classification of biological safety 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., which are not easy to cure after infection . This standard divides the biological safety cabinets into grades I, II, and III, which can be applied to the operation of media of different biological safety levels.
Low Noise Leakproof ULPA Class10 Biosafety Cabinet Level 2 BSC Biosafety Cabinet is a biosafety level 2 (P2) biosafety cabinet

Low Noise Leakproof ULPA Class10 Biosafety Cabinet Level 2 BSC Biosafety Cabinet Precautions:
1. In order to avoid cross-contamination between items, the items needed during the entire work process should be lined up and placed in the Low Noise Leakproof ULPA Class10 Biosafety Cabinet Level 2 BSC Biosafety Cabinet before the work starts, so that there is nothing before the work is completed Items need to be taken out or put in through the air flow compartment. Special attention: no items can be placed on the front and rear return grills to prevent the return grills from being blocked and affecting the air circulation.
2. Before starting work and after finishing the work, the air flow should be maintained for a period of time to complete the self-cleaning process of Low Noise Leakproof ULPA Class10 Biosafety Cabinet Level 2 BSC Biosafety Cabinet. The cabinet should be cleaned and disinfected after each test.
3. During operation, try to minimize the number of in and out of both arms. When entering and exiting the Low Noise Leakproof ULPA Class10 Biosafety Cabinet Level 2 BSC Biosafety Cabinet, the movements should be slow to avoid affecting the normal airflow balance.
4. The movement of items in the cabinet should follow the principle of moving from low pollution to high pollution, and the experiment operation in the cabinet should be carried out from the clean area to the polluted area. Before operation, a towel soaked with disinfectant can be used as a bottom to absorb any droplets that may spill.
5. Try to avoid placing centrifuges, oscillators and other instruments in the Low Noise Leakproof ULPA Class10 Biosafety Cabinet Level 2 BSC Biosafety Cabinet, so as to prevent the particulate matter on the filter membrane from shaking off when the instrument is shaken, causing the cleanliness of the cabinet to decrease; at the same time, these The airflow of the instrument's heat dissipation vent may affect the airflow balance in the cabinet.
6. Low Noise Leakproof ULPA Class10 Biosafety Cabinet Level 2 Open flames cannot be used in the BSC Biosafety Cabinet to prevent the high temperature and fine particles generated during the combustion process from entering the filter membrane and damaging the filter membrane
