The most important function of the fume hood is the exhaust function. In the chemical laboratory, the experimental operation may generate a variety of harmful gases, odor, moisture and flammable, explosive, corrosive substances. In order to protect the safety of users and prevent the spread of contaminants in the laboratory, you should use a small number of fume hood in the vicinity of the laboratory. Especially when you are operating substances the particularly harmful and dangerous gases and producing a lot of hot, you must use walk-in fume hood. The fume hood only supports the auxiliary function of the experimental bench. Taking into account the improvement of the experimental environment, the experiments carried out on the bench gradually transferred to the fume hood, which requires the fume hood to have the most suitable functions for equipment. In particular, most of the new laboratories are required to have air conditioning, so the number of fume hood need to be used should be taken into consideration with air conditioning system plan in the initial stage of the design of the building. As the fume hood occupies a very important position in the biochemical laboratory, the number of using fume hoods increased largely to improve the laboratory environment, labor hygiene conditions, work efficiency and other aspects. Followed by the ventilation pipes, piping, wiring, exhaust have become an important issue in laboratory construction.
The biggest purpose of using the fume hood is to discharge the harmful gases produced in the experiment to protect the health of the experimenter. Therefore, to achieve a high degree of safety and superior operability, the fume hood should have release function, does not reverse function, isolation function, supplementary function, control wind speed function, heat resistance, acid corrosion resistance function and others.
Safety is the biggest mission of the fume hood, the use of fume hood in the laboratory is to ensure the safety of users and to prevent the surrounding environment pollution.
