Safeguards when operating the etelux glove box

Vacuum glove box is widely made use of in industries with superior necessities for gas purification. Even though the existing glove box style and design is far more acceptable and simple to run. Nonetheless, the structure within the glove box is complex, there are numerous vital pieces, and the procedure is slightly inappropriate, which may possibly induce reduction to your experimental benefits. This article introduces you how to the right way use the vacuum glove box, and the safeguards when novices work the glove box.

A person. Perform before procedure:

one. Examine if there is nitrogen in the nitrogen bottle. The nitrogen need to be changed in time. The output tension of nitrogen is set to .4mpa.

two. Check regardless of whether the vacuum pump is turned on normally.

3. Look at no matter if the circulation in the glove box is open. (Purification column-I or purification column-II should open a single of them)

4. Examine the higher restrict stress in the placing should be +one, the lower restrict stress is

5. Verify regardless of whether oxygen and dew stage are usual (oxygen is underneath .1ppm, dew stage is earlier mentioned -forty)

six. The vacuum pump of the more than-bin should be in the usually open point out

two. Procedure notes:

one. The vacuum pump must be stored on during method operation.

two. When the oxygen concentration in the tank exceeds 200PPM, the gear servicing personnel ought to be notified to work the method, if not the h2o and oxygen purification procedure will be ruined.

three. In advance of beginning the cycle, verify whether or not the cabinet is in ailment or regenerating. As the higher than mentioned functions are in progress, it is completely forbidden to cycle.

4 .Two purification columns are unable to be regenerated at the identical time.

A. Right before regeneration, be certain 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 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.
