Cautions Before Operating Glove Box
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 glove box
has a complicated structure, many important parts, and a slight improper
operation may cause loss of your experimental results.
Here's what you should do before operation:
1. Check if 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. (One of the purification column-I or purification column-II
should be opened)
4. The upper limit pressure in the check
settings should be +1, and the lower limit pressure should be 0.
5. Check whether the oxygen and dew point
are normal (oxygen is below 0.1ppm, dew point is above -40)
6.The vacuum pump of the antichamber should
be in the normally open state
