Vacuum glove box is extensively employed in industries with substantial necessities for gas purification. Whilst the present glove box design is more realistic and easy to work. On the other hand, the structure inside of the glove box is sophisticated, there are quite a few essential areas, and the operation is a little incorrect, which may perhaps lead to reduction to your experimental results. This post introduces you how to the right way use the vacuum glove box, and the safety measures when novices operate the glove box.

A single. Function in advance of operation:

1. Examine if there is nitrogen in the nitrogen bottle. The nitrogen need to be replaced in time. The output pressure of nitrogen is established to .4mpa.

2. Verify regardless of whether the vacuum pump is turned on commonly.

3. Examine whether or not the circulation in the glove box is open up. (Purification column-I or purification column-II should really open a person of them)

4. Check out the upper restrict strain in the environment must be +1, the lower limit stress is

5. Look at no matter whether oxygen and dew position are ordinary (oxygen is down below .1ppm, dew issue is higher than -40)

6. The vacuum pump of the around-bin must be in the commonly open condition

two. Operation notes:

one. The vacuum pump need to be saved on through system procedure.

two. When the oxygen concentration in the tank exceeds 200PPM, the machines upkeep personnel need to be notified to operate the procedure, if not the h2o and oxygen purification technique will be damaged.

3. Right before beginning the cycle, check out whether the cabinet is in ailment or innovative technologies glovebox regenerating. As the above mentioned operations are in progress, it is completely forbidden to cycle.

4 .Two purification columns can't be regenerated at the similar time.

A. Right before regeneration, make sure 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.
