Description and structure principle of vacuum glove box

Glove box is a laboratory equipment that fills the box with high-purity inert gas and circularly filters out the active substances It is also called real empty hand box, inert gas protection box, etc Its main function is to remove O2, H2O and organic gas It is widely used in ultrapure environment without water, oxygen and dust, such as: lithium-ion battery and materials, semiconductor, super capacitor, special lamp, laser welding, brazing, material synthesis, OLED, MOCVD, etc It also includes biological applications, such as anaerobic bacteria culture, cell hypoxia culture, etc Although the chemical reaction of this kind of substance can be carried out in a vacuum vessel, it can not be operated, which makes the pre-treatment of chemical reaction samples of this kind of substance very difficult Using vacuum glove box can make this kind of substance operate, react and test freely without oxygen and water, so it has a wide range of applications in chemistry, chemical industry, biology, biology, especially in the preparation and research of some catalysts and organometallic substances (such as M0 source) 2、 This operation box is mainly composed of main box and transition chamber If users have other special requirements, they can also design and manufacture as required There are two (or more) glove operation interfaces on the main box, which are distributed on the front (or front and back) sides of the box, so that the operation box can be operated by one (or several) people at the same time, improving the use efficiency of the box In addition, there are observation windows in the front (or front and back) of the box body, so that the operator can clearly observe the operation process in the box body, so that the operation process can be directly displayed in front of the operator The valve of the transition chamber is provided with an air extraction and inflation nozzle, which can be connected when air extraction or inflation is needed The main box body is also equipped with valves and nozzles, which can be used when it is necessary to maintain the air pressure balance and deflate or inflate the main box body (the three-way valve between the glove mouth can also be used to deflate if necessary) A fluorescent lamp is installed above the front observation window of the main box body The transition chamber is the transition space between the main box body and the external body, which is composed of two sealed doors, two valves and a chamber body The two doors inside and outside can effectively isolate the main box from the outside, so that the things inside and outside the stupid body can enter and exit under the condition that the main box is isolated from the atmosphere, thus avoiding the trouble of repeatedly vacuuming and inflating the main box
