? Bench, fume hoods, laboratory furniture, laboratory equipment Shenzhen Heng Yue Xiang Co., Ltd. is specialized in the production and sale of bench, fume hoods, central bench, medicine cabinets and other laboratory furniture, laboratory equipment manufacturers, our factory has first-class modern production equipment, years of production experience, large-scale production; scientific management; professional technical installers. Both professional design and supervision, we have the spirit of "promoting environmental conservation, science and technology, people-oriented" concept for the majority of users. With the development of China's economy or on whether there has been a qualitative leap in technology, so in this qualitative leap is inseparable from the lab, sophisticated degree of laboratory furniture and equipment directly affects its production or research. That next Heng Yue Xiang company to introduce you to the role of laboratory fume hood equipment. Laboratory fume hood is an indispensable laboratory design is an integral part. In order to make the laboratory staff does not swallowed or inhaled toxic, can cause disease of unknown chemicals and organisms, so the lab needs good ventilation. In order to prevent the absorption of some steam, gases or particulates, fume hood equipment needed to exclude pollution substances. Fume Hood-style structure is down, the top vent, the fan can be installed. OTC has baffles, circuit control touch switches, electrical outlets, etc., perspective window with tempered glass, can move left and right or up and down. For people to operate. The next cabinet is the use of the experimental side station style, there are table above, the following is the cabinet. Countertop and faucet can be installed small cups. Fume hood materials can be divided into steel, wood, all wood, aluminum and wood, steel, PVC and other structures, where the table is in direct contact with the operator, it is generally used solid core physiochemical board, stainless steel, PV, ceramics and other materials. Most of the conventional fume hood timber production, modern multi-coated steel for the manufacture of epoxy resins. Common cabinet width 1000,1200,1500,1800,2000MM several specifications and wide 700-900MM, high 1900-2400MM. Generally available for one to three people simultaneously. Laboratory fume hoods are generally installed against a wall. Middle in front of the fume hood is moved up and down the glass transparent door, opening height generally 100-600MM. Face the door for the experiment, there are connection pipes, sewer, power, vacuum pumps, gas lines and other experiments required, there are lighting with protective cover. Air from the front of the cabinet above the exhaust fan pulled out, or through pipes lead to elsewhere (called full ventilation), or the use of re-circulated through a filter (called ductless ventilation). Fume hood exhaust is generally too small in front of the glass door open too much time alerts, alert the operator should pay attention to. Internal fan speed and light switches have adjustable. When the operator should be used as much as possible to lower the glass door, through the door into his hand inside the experiment. Because the exhaust fan exhaust through the open door inward, under normal circumstances, a large number of harmful gases do not overflow.
