Basic principle and application of vacuum glove box

The vacuum glove box is a laboratory equipment that fills a high-purity inert gas into the box and circulates the active material therein. Also known as glove boxes, inert gas protection boxes, dry boxes, etc. Mainly for the removal of O2, H2O, organic gases.

The basic operation process of the vacuum glove box: 1) connect the inert gas to the gas inlet, 2) connect the mechanical pump to the vacuum interface, 3) check the transition chamber, open the outer door to close the inner door, 4) close the glove cover, 5) pump vacuum to -0.1Mp, Turn off the vacuum pump, 6) fill the inert gas to 0Mp, close the intake valve. If there are other devices, it should be turned on in this part to prepare the environment inside the glove box to the required state.

Vacuum glove boxes are widely used in anhydrous, oxygen-free, dust-free ultra-pure environments, such as: lithium-ion batteries and materials, semiconductors, super capacitors, special lamps, laser welding, brazing, etc. Or the cultivation of anaerobic microorganisms, etc. in an anaerobic environment in the field of biological sciences.
