Purification Glove Box

Purification Glove Box is laboratory equipment designed to create a controlled atmosphere by filling the chamber with high-purity inert gas while continuously filtering out impurities such as O₂, H₂O, and organic vapors. Also known as a vacuum glove box or inert gas protection chamber, its primary function is to eliminate oxygen, moisture, and organic gases. It is widely used in ultra-clean environments free from O₂, H₂O, and dust—such as in lithium-ion battery and material research, semiconductor manufacturing, supercapacitors, specialized lighting, laser welding, brazing, material synthesis, OLED, and MOCVD processes. Additionally, it supports biological applications including anaerobic bacterial culture and hypoxic cell incubation.

Working Principle
The glove box operates through a closed-loop gas circulation system between the main chamber and the purification column, which contains adsorbents for H₂O and O₂ removal. Under PLC control and monitoring, the working gas flows continuously via pipelines and circulation blowers. As the gas passes through the purification column, moisture and oxygen are adsorbed, and the purified gas returns to the chamber. Over repeated cycles, the concentrations of H₂O and O₂ in the chamber gradually decrease, ultimately reaching levels below 1 ppm. The purification column can become saturated after prolonged use but is regenerable for repeated operation.
