The main applications of secondary biosafety cabinets

The main function of a secondary biosafety cabinet is to provide protection for laboratory personnel, environment, and experimental samples. This safety cabinet is a common equipment in laboratories, which can provide protection for both experimenters and experimental samples. Suitable for handling moderately harmful microorganisms, such as some pathogens that may be transmitted through the air. The BSC-II biosafety cabinet is a fully ventilated device in which no air circulates inside the cabinet, thus providing basic biological and chemical protection. The key component of these safety cabinets is the HEPA filter, which is responsible for removing harmful biological aerosols that may be generated during operation to protect the laboratory environment and personnel safety.
The main application industries of secondary biosafety cabinets are:
1. Biopharmaceutical industry: In biotechnology companies and pharmaceutical enterprises, biosafety cabinets are used in vaccine production, antibiotic sensitivity testing, and other operations involving potential pathogenic microorganisms.
2. Higher education and research institutions: When conducting laboratory research in biomedical, microbiology, and related fields, universities and research institutes use biosafety cabinets to ensure the safety of scientific research work.
3. Public health and environmental protection agencies: When handling samples that may pose a threat to public health or the environment, relevant agencies will use biosafety cabinets to prevent contamination and cross infection.
4. Medical and health industry: Hospitals, disease control centers, laboratories and other medical institutions use biosafety cabinets to protect staff and the environment when handling infectious materials, pathogen cultivation and diagnostic tests.
As for the maintenance methods of secondary biosafety cabinets, they mainly include the following aspects:
1. Preparation work: Before starting work, the surface contamination inside the cabinet should be cleaned, and the required items should be placed reasonably to ensure smooth and unobstructed air flow inside the cabinet.
2. Fan and filter inspection: Regularly check the operation status of the fan and measure whether the wind speed in the working area meets the standards. If the wind speed does not meet the standard, consider replacing the HEPA filter.
3. UV sterilization: When using equipment with UV sterilization function, samples resistant to UV damage can be placed for disinfection treatment before starting the experiment.
4. External cleaning: Use soft fabric to wipe and maintain the exterior of the safety cabinet to ensure its cleanliness.
