Purification Glove Box

A Purification Glove Box is a specialized laboratory system designed to maintain an ultra-clean, oxygen-free and moisture-free environment by continuously circulating high-purity inert gas through the sealed chamber. Often referred to as an inert atmosphere glove box or gas-protection workstation, it effectively removes O₂, H₂O, and organic contaminants. This equipment is essential in research areas that require strictly controlled conditions—such as lithium battery development, advanced materials engineering, semiconductor fabrication, supercapacitor studies, precision lighting, welding technologies, OLED and MOCVD processes. It is also applicable in biological sciences, including anaerobic microbial cultivation and low-oxygen cell culture.

Working Principle

The glove box uses a fully sealed gas-circulation loop that connects the main chamber with the purification column filled with high-efficiency adsorbents for moisture and oxygen removal. Under PLC supervision, the system drives the working gas through pipelines and circulation blowers to pass repeatedly through the purification material. With each cycle, impurities are trapped, and purified gas re-enters the chamber. Over time, the internal levels of H₂O and O₂ drop to below 1 ppm. When the purification material becomes saturated after extended use, it can be regenerated to restore full performance and continue long-term operation.
