The Purpose and Structure of the Glove Box

The glove box is laboratory equipment that fills the chamber with high-purity inert gas and circulates and filters out the active substances in it. 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 without O2, H2O, 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 and cell hypoxia culture.

The purpose of the glove box

The glove box operation needs to be isolated from the air for experiments. For example, metal lithium reacts with oxygen. Some reactions need to be carried out in an inert gas such as argon. Use an open (unshielded) radioactive source, protected with lead and lead glass. Protect experimenters from toxic chemicals. It is more completely isolated than the fume hood, but it is more inconvenient to operate. Mainly used in situations where the toxicity is particularly strong. Conduct experiments that may cause serious biological hazards, such as virulent bacteria.

Glove box structure principle

The 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 body of the glove box, which are distributed on the front side (or front and back sides) of the box body. This allows the operation box to be operated by one (or several) people at the same time, which improves the efficiency of the chamber. In addition, there are observation windows in the front (or front and back) of the glove box, so that the operator can clearly observe the operation process inside the box, so that the operation process can be displayed directly in front of the operator. The valve of the transition chamber of the glove box is equipped with suction and charging nozzles, which can be connected when suction or charging is required. Valves and nozzles are also installed on the main box of the glove box. Users can use it when deflating or inflating the main box 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.

The glove box transition chamber is used as the transition space between the main box body and the outside of the box body, and 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 world, so that things inside and outside the box 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.
