Safeguards when operating the etelux glove box

Esther Karn (2020-08-17)

vacuum glovebox glove box is broadly utilised in industries with substantial needs for gas purification. Whilst the recent glove box structure is extra fair and uncomplicated to operate. Nevertheless, the composition inside the glove box is complicated, there are numerous vital pieces, and the procedure is somewhat inappropriate, which may well cause loss to your experimental final results. This report introduces you how to appropriately use the vacuum glove box, and the safeguards when novices work the glove box.

1. Operate right before procedure:

one. Verify if there is nitrogen in the nitrogen bottle. The nitrogen need to be replaced in time. The output stress of nitrogen is established to .4mpa.

2. Verify no matter if the vacuum pump is turned on typically.

3. Test regardless of whether the circulation in the glove box is open up. (Purification column-I or purification column-II really should open up a single of them)

four. Check the upper restrict pressure in the location should be +1, the reduce limit force is

five. Test regardless of whether oxygen and dew level are normal (oxygen is below .1ppm, dew place is above -40)

6. The vacuum pump of the above-bin ought to be in the typically open up condition

two. Procedure notes:

one. The vacuum pump need to be held on during procedure procedure.

2. When the oxygen focus in the tank exceeds 200PPM, the tools maintenance staff ought to be notified to run the technique, if not the water and oxygen purification process will be destroyed.

three. Before beginning the cycle, look at regardless of whether the cabinet is in ailment or regenerating. As the over stated operations are in progress, it is totally forbidden to cycle.

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

A. Right 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 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.
