<img src=";/> Vacuum glove box is broadly used in industries with higher needs for gasoline purification. Though the recent glove box layout is a lot more reasonable and effortless to function. Even so, the composition inside the glove box is complex, there are several crucial elements, and the procedure is somewhat incorrect, which could cause loss to your experimental results. This post introduces you how to accurately use the vacuum glove box, and the safety measures when novices function the glove box.
A single. Operate before procedure:
one. Check out if there is nitrogen in the nitrogen bottle. The nitrogen should be changed in time. The output stress of nitrogen is established to .4mpa.
two. Examine no matter whether the vacuum pump is turned on usually.
3. Verify whether or not the circulation in the glove box is open. (Purification column-I or purification column-II ought to open up one particular of them)
4. Check out the higher restrict pressure in the environment need to be +one, the reduce restrict force is
five. Verify regardless of whether oxygen and dew point are regular (oxygen is underneath .1ppm, dew level is above -40)
six. The vacuum pump of the over-bin ought to be in the generally open point out
two. Procedure notes:
1. The vacuum pump must be retained on in the course of program procedure.
2. When the oxygen focus in the tank exceeds 200PPM, the gear upkeep personnel should be notified to operate the method, in any other case the drinking water and oxygen purification program will be damaged.

4 .Two purification columns can not be regenerated at the exact same time.
A. Before regeneration, make sure that the glove box has been cleaned with inert gasoline (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 <a href=";>glovebox</a> 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.
