PCR laboratory planning sterile laboratory clean laboratory biosafety PCR laboratory construction program includes: building layout and decoration, air conditioning, water supply and drainage, gas supply, electrical design, centralized control, security, construction process, testing, training and many other aspects. However, at the same time, energy is often consumed in large quantities, and thus the requirements for ventilation control systems in PCR laboratories are getting higher and higher, from the early fixed air volume, bistable type, variable air volume systems, to the latest adaptive control systems a both safe , but also to meet the need to save energy.
Ventilation cabinet is one of the most commonly used local exhaust equipment in PCR laboratories, and his performance depends mainly on the speed of air movement through the ventilation cabinet. Factors affecting the frontal velocity and air movement are eddy currents, cabinet inlet shape, heat load, mechanical action, exhaust hole design and condensate barrier. In addition, it is also related to the performance of his fire resistance, corrosion resistance, ease of cleaning and the ability to collect certain contaminants before they enter the exhaust system. It is generally accepted that fume hoods in PCR laboratories should be able to accommodate flammable liquids and gases, and that the structural materials should have a fire resistance of several minutes to keep the fume hood intact and to seal the fire out in a timely manner.
