Vacuum glove box is widely used in industries with high requirements for gas purification. Although the current glove box design is more reasonable and easy to operate. However, the structure inside the glove box is complicated, there are many important parts, and the operation is slightly improper, which may cause loss to your experimental results. This article introduces you to the precautions before operating the glove box.
Work before operating the glove box:
1. Check whether there is nitrogen in the nitrogen bottle. The nitrogen should be replaced in time. The output pressure of nitrogen is set to 0.5mpa.
2. Check whether the vacuum pump is turned on normally.
3. Check whether the circulation in the glove box is open. (Purification column-I or purification column-II should open one of them)
4. Check the upper limit pressure in the setting should be +1, the lower limit pressure is 0
5. Check whether oxygen and dew point are normal (oxygen is below 0.1ppm, dew point is above -40)
6. The vacuum pump in the over cabin should be in the normally open state
