Biological safety cabinet introduction 2021-01-01
Some people may think that the biosafety cabinet is nothing more than an iron box with a fan and some HEPA filters; in fact, the biosafety cabinet is much more complicated. Similarly, maintaining the safety of a biosafety cabinet is much more complicated than "regular replacement of filters." The purpose of this paper is to solve the problem of the safety performance of safety cabinets, and to provide guidance for laboratory staff, management personnel and other relevant personnel involved in the safety and maintenance of safety cabinets. filter The filter is a key component in the biosafety cabinet, which acts to filter bacteria and dust particles to purify the gas that is blown into the safe cabinet and discharged. The filter used in the safety cabinet must have sufficient filtration efficiency, otherwise it will not protect against biological hazards. The filter material should be silicate fiberglass. At present, HEPA high-efficiency filters with a cut-off efficiency of 99.99% for 0.3μm dust particles and ULPA ultra-high efficiency filters with 99.9998% cut-off efficiency are commonly used in safety cabinets. The latter has better filtration efficiency, tighter structure and larger unit filtration area, providing the equivalent of ISO3 cleanliness for the work area. Fan system A fan system that meets the national standard of the safety cabinet shall have the following functions: automatic air volume compensation function, which can automatically compensate the air volume to keep the air flow rate constant when the filter load wind pressure drops to a certain range; the motor has thermal protection function, Stable operation at 1.15 times rated voltage.

Nine tips for clean room energy saving 2020-04-11
Nine tips for clean room energy saving There are plenty of energy-saving places in the clean room, such as heating, ventilation and air conditioning, process cooling, compressed air and some other facilities. The HVAC system consumes more than half the electricity used by the entire wafer fabrication facility. The reason for the large amount of wasted power and HVAC capacity surplus is largely due to the shortcuts in the design and construction of the plant, as much as possible to compress the initial investment, regardless of the later operating costs. Efficient design and high efficiency equipment require a large upfront investment. The so-called shortcuts and cost reductions of "small places to save a lot of waste" will result in reduced plant performance and increased energy consumption. Reconstruction of completed factories often falls into a meaningless economic vortex. Upgraded investment recovery rates are usually much higher than direct purchases of new equipment. Most of the plant equipment refurbishment has a payback period of no more than two years-that is, usually the investment recovery rate is at least 50%, compared to 10% to 15% compared to investing in new fixed assets. These conditions reduce the competitiveness of companies and the interests of investment shareholders. In today's highly developed industries, plant operations and product design require refo
