The danger of not timely replacement of high-efficiency filters in biological safety cabinets
The danger of not timely replacement of high-efficiency filters in biological safety cabinetsWhat is a high-efficiency filter in a biological safety cabinet? First of all, the biological safety cabinet is designed for the operation of primary cultures, bacterial strains diagnostic specimens, and other infectious experimental materials, used to protect the operator himself, the laboratory environment, and experimental materials, so that they avoid being exposed to infectious aerosols and spattering that may be generated during the above operation, in which the high-efficiency air filters are the core components of the biological safety cabinet, which belongs to the category of wearable consumables, and plays a very important role in the safety cabinet. Safety cabinets play a very important role, and it is recommended that the biological safety cabinets at least once a year to detect, at least once every two years comprehensive maintenance, otherwise it will cause what harm?1, high-efficiency filters gathered on a large number of bacteria, dust, and a variety of hazardous factors, directly affecting the normal airflow of the biological safety cabinet, over time, the hazardous factors will be circulating with the airflow, which will lead to experimental samples, operators and the environment are unprotected. 2, in the unsafe "safety" cabinet operation, directly affecting the results of experiments or samples are contaminated, which may lead to 17% of medical errors. 3, biological safety cabinets can be used less frequently to extend the maintenance? Of course not! Bio-safety cabinet high-efficiency filter itself has a long life expectancy, long time, its filtering effect will be reduced, which may also cause the above hazards. |
