The life of a biosafety cabinet is 8 years, but the high efficiency biosafety cabinet filter has a service life. As the life cycle increases, dust bacteria, small aerosol particles, etc. will accumulate in the filter, resulting in increased pressure loss of the high efficiency filter. . Affecting the airflow in the biosafety cabinet, the inflow wind speed and the outflow wind speed are reduced, and the number of dust particles is increased. The user is not noticeable. In fact, the biosafety cabinet is not really safe at this time! Has caused intangible harm to the user. The user should run the equipment in a clean air background. Long-term operation in a poor air environment can result in frequent replacement of high efficiency filters. Otherwise it will affect the safety performance of the device.
The biological safety cabinet works by keeping the negative pressure inside the biological safety cabinet, allowing the airflow to enter the safety cabinet from the outside, preventing the overflow of pathogenic microorganisms in the cabinet, thereby protecting the experimental operator, while the circulating air and the exhaust air are filtered through the high efficiency filter. It also protects products and labs. The filter is one of the more important aspects, the protection of the operator protection, product protection and cross-contamination after the filter is replaced by the biosafety cabinet.
Check daily to ensure that the seal between the filter and the system is secure and leak-free. In the event of a leak, apply a wrench to tighten the screw cap. Since the filter may be filled with biohazardous materials, it should be replaced or repaired by a professional. It is necessary to carry out the safety cabinet before replacement and/or repair. Disinfect and clean.
