Vacuum glove box is broadly made use of in industries with high requirements for gas purification. Whilst the present glove box design is additional affordable and simple to function. On the other hand, the structure inside of the glove box is intricate, there are numerous vital areas, and the procedure is marginally inappropriate, which might cause reduction to your experimental outcomes. This posting introduces you how to correctly use the vacuum glove box, and the safeguards when novices function the glove box.
One. Function right before procedure:
one. Look at if there is nitrogen in the nitrogen bottle. The nitrogen ought to be changed in time. The output tension of nitrogen is set to .4mpa.
two. Examine whether or not the vacuum pump is turned on commonly.
3. Test whether or not the circulation in the glove box is open. (Purification column-I or purification column-II really should open up a person of them)
four. Look at the higher limit stress in the location ought to be +1, the lessen limit stress is
five. Check whether or not oxygen and dew point are ordinary (oxygen is under .1ppm, dew level is higher than -forty)
6. The vacuum pump of the about-bin really should be in the usually open up condition
two. Procedure notes:
one. The vacuum pump ought to be retained on through technique procedure.
2. When the oxygen focus in the tank exceeds 200PPM, the machines servicing staff must be notified to work the procedure, if not the water and oxygen purification process will be destroyed.
3. Before setting up the cycle, look at no matter whether the cabinet is in issue or regenerating. As the previously mentioned outlined operations are in development, it is completely forbidden to cycle.
four .Two purification columns can't be regenerated at the exact time.
A. Right before regeneration, assure that the glove box has been cleaned with
inert atmosphere glove box 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.
