The function introduction and purchase method of the laboratory all steel fume hood:

      Laboratory fume hoods are one of the most important laboratory equipment in the laboratory, because operators often do experiments in the laboratory that can vent toxic gases, and the maximum function of the fume hood is to deal with these toxic chemicals. Effective removal. This allows the laboratory to have a good air environment.

      Commonly used materials for general fume hoods include all-steel, steel-wood, all-wood, aluminum-wood, plastic-steel, pvc structures, etc. The countertops that are in direct contact with the operator are generally constructed of solid core physicochemical plates, pvc, stainless steel plates, and ceramic materials. The function of the fume hood is to remove harmful gases from the laboratory and protect the health of the personnel, so it must have a high degree of safety and operability. So the functions we should have when purchasing a laboratory fume hood are:

       1, heat, acid and alkali, corrosion resistance, such as to meet such requirements, the overall material of the fume hood should be stainless steel or pvc structure. All steel fume hood

       2, isolation function, there should be a window that does not slide in front of the fume hood, playing a separation role.

       3, release function, the harmful gas generated inside the fume hood is used to absorb the gas outside the cabinet, so that it is diluted to exclude the outdoor mechanism.

       4, supplementary function, there should be a pipe or alternative device for inhaling air outside the fume hood

       5, no backflow function, a fume hood and a ventilator are connected by a single pipe, can not be connected by a single pipe, the ventilator is installed at the end of the pipe (or at the top of the layer) as much as possible.
