The glove box is laboratory equipment that fills the box with high-purity inert gas and circulates and filters out the active substances in it. Also called vacuum glove box, inert gas protection box, etc. The main function is to remove O2, H2O, and organic gases.

   is widely used in ultra-pure environments without water, oxygen and dust, such as: lithium-ion batteries and materials, semiconductors, super capacitors, special lamps, laser welding, brazing, material synthesis, OLED, MOCVD, etc. It also includes biological applications, such as anaerobic bacteria culture, cell hypoxia culture, etc.


1. The vacuum pump should be kept on during the work of the glove box system.

 

2. When the oxygen concentration in the box exceeds 200PPM, the equipment maintenance personnel should be notified to perform system operation, otherwise the water and oxygen purification system will be damaged. To

 

3. Check before the glove box starts the cycle to see if the box is in condition or regeneration. If the above-mentioned operation is in progress, the loop must be prohibited.

 

4. Two purification columns cannot be regenerated at the same time.

 

A. Before regeneration, ensure that the glove box has been cleaned with inert gas (H2O<200ppm) to ensure sufficient regeneration gas supply. The regeneration gas pressure is 0.06-0.08mpa.

 

B. Before starting the regeneration of the glove box, please confirm that the corresponding purification column cycle is closed.

 

C. The glove box regeneration process takes 24 hours. Once executed, the regeneration gas cannot be disconnected. Pay attention to the amount of regeneration gas and adjust the pressure of regeneration gas appropriately to ensure sufficient supply of regeneration gas during these 3 hours. , The regeneration source can be turned off after the 6th hour.

 

D. The vacuum pump cannot be turned off during the regeneration process of the glove box, and do not touch the top of the purification column to prevent scalding.

 

E. Once the regeneration is terminated unexpectedly, please ensure that the regeneration and circulation of the purification column cannot be restarted within 12 hours, otherwise the equipment will be damaged.

 

5. When working in the glove box, care should be taken to protect the working gloves from damage.
