Model: TOB-GLOVE BOX

This is a compact glovebox that connects a two-station glovebox to a single-station glovebox via a T-transition chamber. It has single-side operation, PLC control and touch screen operation functions. Integrated single column purification unit, vacuum pump, holder, one with angled operating surface and removable safety glass front window, etc.

Under standard conditions, that is, 20℃constant temperature, a standard atmospheric pressure, 99.999% inert air source, water oxygen index is less than 0.1 ppm.

Function of glove box

The inert gas in the glove box is closed by the circulating fan and purifier to remove water and oxygen constantly.

Automatic controlled regeneration

Dehydrating and deoxygenating materials can be regenerated, and the regeneration process is controlled by the program.

Automatic cleaning

Air displacement in the glove box is accomplished by an automatically controlled cleaning valve.

Tank pressure control

The pressure inside the glove box is automatically controlled by PLC. The working pressure can be set freely within +/- 15mbar. When it exceeds +/- 16mbar, the system will start automatic protection.

Vacuum pump automatic control

The vacuum pump must be automatically started when the system needs it.
