1. Purpose. The vacuum glove box is very sensitive to O2 and H2O in the chemical reaction and the pre-treatment of the test sample, which cannot be carried out in the general environment. Although the chemical reaction of this type of substance can be carried out in a vacuum container, it cannot be operated, which makes the pretreatment of the chemical reaction sample of this type of substance very difficult. The use of a vacuum glove box allows these substances to be freely operated, reacted and tested in the absence of oxygen and water. Therefore, it is used in chemistry, chemical industry, biology, and biology, especially in certain catalysts and metal organic substances (such as M0 sources, etc.) ) Has a wide range of uses in preparation and research.
2. Structure and Principle. The vacuum glove box is mainly composed of the main box body and the transition chamber. If users have other special requirements, they can also be designed and manufactured according to their needs. There are two (or more than two) glove operation interfaces on the main box of the vacuum glove box, which are distributed on the front (or front and back sides) of the box. This allows the operation box to be operated by one (or several) people at the same time, which improves Improve the efficiency of the cabinet. In addition, there are observation windows on the front (or front and back) of the box, so that the operator can clearly observe the operation process inside the box, making the operation process intuitively displayed in front of the operator. The valve of the transition chamber has suction and charging nozzles, which can be connected when suction or charging is required. Valves and nozzles are also installed on the main box body, which can be used when deflating or inflating the main box body to maintain air pressure balance (the three-way valve between the glove ports can also be used to deflate if necessary). Illuminating fluorescent lamps are installed above the front observation window of the main box of the vacuum glove box. The transition chamber is used as the transition space between the main box body and the outside of the stupid body. It is composed of two sealed doors, two valves and a chamber body. The two doors inside and outside can effectively isolate the connection between the main box and the outside world, so that things inside and outside the body can enter and exit when the main box is isolated from the atmosphere, thereby avoiding the trouble of repeatedly vacuuming and inflating the main box.
