Revealing the Secrets of Laboratory Air Protection Product!
Biological safety cabinets, fume hoods, and laminar flow cabinets are common equipment in scientific research laboratories and play an important role in laboratory air protection. But the three are not the same in application.
Applications of Biological Safety Cabinet
Biological safety cabinets are key equipment in laboratories such as microbiology, biomedicine, genetic recombination, animal experiments and biological products. They can prevent microbial contamination and protect experimental personnel. Especially in occasions where operators need to take protective measures, such as medical and health, pharmaceutical, scientific research, etc., a sterile, dust-free and safe working environment is provided for bacterial culture.
The working principle of the biological safety cabinet is to suck the air inside the cabinet outward to maintain a negative pressure state in the cabinet and protect workers through vertical airflow. The outside air is filtered by a high-efficiency particulate air filter (HEPA filter) and then enters 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.
Applications of Fume Hood
The fume hood is a large piece of equipment in a chemical laboratory. The purpose is to reduce the contact between experimenters and harmful gases. It can discharge chemical smoke, dust and toxic gases generated in chemical experiments, protecting workers and the laboratory environment.
Applications of Laminar Flow Cabinet
The laminar flow cabinet is designed to protect the test items or products by blowing vertical or horizontal laminar air through the work area to prevent the test items or products from being contaminated by dust or bacteria outside the work area. The laminar flow cabinet is suitable for non-toxic and harmless operating objects. It is generally used in hospitals, biopharmaceuticals, food, medical science experiments, optics, electronics, sterile room experiments, etc. that require local cleanliness and Bacterial working environment of scientific research and production departments.
In general, laboratory laminar flow cabinets provide a clean working environment, biological safety cabinets are used to prevent the contamination and spread of biohazardous substances, and fume hoods are used to control and eliminate harmful gases, vapors, or dusts. Each device has its specific application scenarios and functions. Select the appropriate device according to the laboratory needs to ensure the safety and accuracy of the experiment.
