Vacuum glove box is commonly applied in industries with higher requirements for gas purification. While the present-day glove box style and design is far more fair and easy to run. Even so, the construction within the glove box is sophisticated, there are a lot of crucial parts, and the operation is a bit inappropriate, which may result in loss to your experimental benefits. This short article introduces you how to appropriately use the vacuum glove box, and the safety measures when novices run the glove box.

A single. Function prior to procedure:

one. Examine if there is nitrogen in the nitrogen bottle. The nitrogen should really be changed in time. The output stress of nitrogen is established to .4mpa.

2. Look at no matter if the vacuum pump is turned on ordinarily.

3. Examine no matter if the circulation in the glove box is open. (Purification column-I or purification column-II need to open up a single of them)

4. Examine the upper limit strain in the setting should be +1, the reduce restrict stress is

5. Verify whether or not oxygen and dew place are typical (oxygen is underneath .1ppm, dew issue is higher than -forty)

six. The vacuum pump of the around-bin really should be in the normally open up condition

two. Operation notes:

one. The vacuum pump should really be retained on in the course of system procedure.

two. When the oxygen focus in the tank exceeds 200PPM, the devices upkeep staff should be notified to function the technique, usually the drinking water and oxygen purification method will be weakened.

three. Just before beginning the cycle, verify whether or not the cupboard is in affliction or regenerating. As the over pointed out operations are in development, it is absolutely forbidden to cycle.

four .Two purification columns can not be regenerated at the identical time.

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

B. Before starting regeneration, please make sure that the corresponding purification column circulation is closed.

C. The regeneration process takes 24 hours. Once the execution cannot be disconnected, the regeneration gas should be passed 3-6 hours after the regeneration starts. Pay attention to the amount of regeneration gas, adjust the pressure of the regeneration gas appropriately, and ensure the sufficient supply of regeneration gas in these 3 hours. After 6 hours the regeneration origin can be turned off.

D. The vacuum pump cannot be turned off during the regeneration process. Do not touch the top of the purification column to prevent burns.

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

5. Care should be taken to protect the work gloves from being damaged during the operation.
