I. Purification SystemThe working principle of a glove box.
The box body and the gas purification system form a sealed working environment. Inert gas or nitrogen is introduced into the box body, and active substances are circulated and removed, ensuring the system ultimately maintains a highly clean and high-purity inert gas environment (both water and oxygen levels can be achieved).1ppmThe following devices).
Mainly forO2 , H2Oof removal.
II. Purification SystemApplication fields of glove boxes
1.Applied in ultra-pure working environments that require the absence of water, oxygen, and dust.

III.Technical Indicators
| Under standard conditions, the water content inside the tank (Note: Standard conditions refer to one atmosphere of pressure and a constant temperature of 20°C) | ≤1ppm |
| Under standard conditions, the oxygen content inside the box is (Note: Standard conditions refer to one atmosphere of pressure and a constant temperature of 20°C) | ≤1ppm |
The transition chamber can withstand a vacuum level value. | ＜100pa |
Leakage rate | ≤ 0.05vol%/h |
Leakage rate≤0.05Vol%/ h；
Leak rate conversion:
Assume the volume of the box is1m³, leakage rate of0.05Vol%/h。
Convert to volume:0.05Vol%/ h×1m³=0.0005m³=0.5L, meaning: the leakage rate per hour is 0.5L.
Calculate the hourly oxygen leakage rate, based on the oxygen content in the air being approximately21% calculation:
0.5L×0.21=0.105L； 0.105L÷1000L/m³=0.000105m³。
0.000105×1000000=105ppm。
Therefore, under shutdown conditions, when no air is supplied to the enclosure and the enclosure pressure is maintained at a slight positive pressure:When the oxygen content is not higher than 105 ppm after 1 hour, the leakage rate is considered to be ≤0.05Vol%/h。
IV.The functions implemented by the system
◎ Manual/automatic control of cabinet pressure;
◎ Purification status of the manual/automatic control system;
◎Automatic control of the reduction process in the gas purification system;
◎ Operation errors and warning prompts of the program control system;
◎ System control parameter settings;
◎ Check system history records;
◎System actuator operating condition detection.
◎The touchscreen instantly displays the chamber pressure value, water content value, and oxygen content value.
◎ Reduction and Regeneration: The purification system uses reduction-regenerable purification materials internally, with the reduction process automatically controlled by the system. During reduction and regeneration, it is necessary to supply power and provide a mixed gas of hydrogen (5-10%) and inert gas.
