The main function of fume hood is exhaust function

Is mainly in the role of the fume hood exhaust effect, in the chemical laboratory, experimental operation produce a variety of harmful gases, odor, moisture and inflammable, explosive, corrosive substances, in order to protect for safety, to prevent the spread of pollutants to the laboratory, in the vicinity of pollution sources to be used for ventilation cabinet, less fume hood for the Numbers before, only in particularly harmful and dangerous gases and produce a large number of experiments is used to heat. The fume hood shall only serve as an auxiliary platform. In recent years, in order to improve the experimental conditions, the experiments carried out on the experimental platform are gradually transferred to the fume hood, which requires that the fume hood should have the function suitable for the equipment. In particular, most of the newly built laboratories require air conditioning, so the number of units used for fume hoods should be included in the air conditioning system plan during the initial design phase of the building. As fume hood occupies a very important position in biochemical laboratory, the number of fume hood used in biochemical laboratory has increased dramatically in terms of improving laboratory conditions, improving labor hygiene conditions and improving work efficiency. The following is the ventilation duct, piping, wiring, ventilation and so on have become an important subject of laboratory construction. We also sell clean sampling vehicle and biosafety cabinet.
