The glove box is a laboratory device that fills a high-purity inert gas into the chamber and circulates and filters out the active substances therein. Also called vacuum glove box, inert gas protection box, etc.

The main function of the glove box is to remove O2, H2O and organic gases. Glove boxes are widely used in ultra-pure environments free of H2O, O2, and dust, such as: lithium-ion batteries and materials, semiconductors, super capacitors, special lamps, laser welding, brazing, material synthesis, OLED, MOCVD, etc. It also includes biological applications, such as anaerobic bacteria culture, cell hypoxia culture, etc.

The use of glove box

The operation of the glove box needs to be isolated from the air for experiments, such as the reaction of lithium metal with oxygen, and some reactions need to be performed in an inert gas environment such as argon. Use an open (unshielded) radioactive source and protect it with lead and lead glass. Protect experimenters from toxic chemicals. It is more isolated than a fume hood. It is mainly used in cases with particularly high toxicity. Conduct experiments that may cause serious biological hazards, such as potent pathogens.

Structure principle of glove box

The glove box is mainly composed of the main chamber body and the antechambers. If users have other special requirements, they can also design and manufacture according to their needs.

There are two (or more than two) glove operation interfaces on the main chamber of the glove box, which are distributed on the front side (or front and back sides) of the chamber body, which makes the operation chamber can be operated by one (or several) people at the same time, which improves the efficiency of the chamber. In addition, there are observation windows on the front (or front and back) of the glove box body. The operator can clearly observe the operation process in the chamber body, so that the operation process is intuitively displayed in front of the operator. The valve of the antechamber of the glove box has suction and inflation joints, which can be connected when the suction or inflation is needed. The main antechamber of the glove box is also equipped with a valve and a mouthpiece, which can be used when the user needs to maintain the air pressure balance and deflate or inflate the main chamber. An illuminated fluorescent lamp is installed above the front observation window of the main chamber.

The glove box antechamber is used as the transition space between the main chamber, and 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 cabinet and the outside world, so that the inside and outside of the cabinet can enter and exit when the main cabinet is isolated from the atmosphere, thus avoiding the trouble of repeatedly vacuuming and inflating the main cabinet.
