Purification glove box is a kind of laboratory device which can be filled with a high purity inert gas into the box and active substances can be filtered out of the box circularly. It is also called “vacuum glove box with water and oxygen removal”, and “inert gas purification glove box”. Main functions of this kind of glove box: water content removal, oxygen content removal, other organic gas removal. It is widely used for making high pure environment without water, oxygen and dust content.

Working principle
The box and purification system are connected together and they both form a well-sealed working environment. When inert gas or nitrogen is filled into the box continuously, the active substances inside the box shall be removed circularly out of the box to keep the inner box in a high cleanness and a high purity inert gas environment (water content≤1 ppm, oxygen content ≤1 ppm) all the time.
