Replace the biosafety cabinet filter
The biosafety cabinet filter is usually built into the biosafety cabinet and is divided into two upper and lower pieces. It is a core component of the biosafety cabinet and an important component. If you use the biosafety cabinet without replacing the filter in time, there is no safety in use and there is a risk of fatal aerosol leakage. The biosafety cabinet filter life is generally 1.5-2 years, and the biosafety cabinet must be placed in a clean environment for operation.
Biosafety cabinet USA AAF high efficiency filter membrane Features: Imported high efficiency filter adopts HEPA/ULPA filtration efficiency of over 99.999%, meeting the requirements of temperature, humidity, corrosion resistance and mechanical strength under normal conditions.
Before the high-efficiency filter is replaced, the inner surface of the cabinet and the original ultra-high efficiency filter must be fumigated with formaldehyde. When replacing, the hand and body may not be operated. The operator must wear protective clothing and masks and small feet gloves. The removed filter should be sealed immediately into a plastic bag, used gloves, protective clothing, etc., treated as medical waste. When installing a new filter, do not put your head and body into the cabinet, and work with great care.
The importance of replacing filters
It is very important to replace the filter in time. It is easy to cause the biosafety cabinet after one year of use.
1. A large amount of bacteria, dust and various risk factors are collected on the filter.
2. Blocking the normal air supply of the filter, affecting the air curtain of the safety cabinet, indirectly affecting the safety of the user of the equipment
3. The vertical descending airflow passes through the filter, and the easily contaminated bacteria fall on the test bench, directly affecting the results of the experiment, leading to misdiagnosis and endangering the patient's life.
4. If there is a hazardous aerosol leak, it will be very dangerous for the user of the equipment to be exposed to an environment that is hazardous to aerosols, which will directly affect life safety.
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.
Why replace the filter:
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.
