Safeguards when working the Nichwell glove box
Vacuum glove box is extensively employed in industries with high needs for gas purification. Despite the fact that the recent glove box design and style is far more reasonable and straightforward to function. Nevertheless, the composition inside the glove box is difficult, there are numerous essential components, and the operation is marginally improper, which might result in reduction to your experimental results. This write-up introduces you how to accurately use the vacuum glove box, and the safety measures when novices function the glove box.

A single. Function ahead of operation:

1. Check out if there is nitrogen in the nitrogen bottle. The nitrogen must be replaced in time. The output stress of nitrogen is established to .4mpa.

2. Check no matter whether the vacuum pump is turned on usually.

3. Check out no matter whether the circulation in the glove box is open. (Purification column-I or purification column-II need to open one of them)

4. Examine the upper restrict stress in the environment should be +one, the reduced limit stress is

5. Check out regardless of whether oxygen and dew level are standard (oxygen is beneath .1ppm, dew point is previously mentioned -forty)

six. The vacuum pump of the above-bin must be in the generally open up condition

two. Operation notes:

1. The vacuum pump need to be kept on in the course of technique procedure.

2. When the oxygen focus in the tank exceeds 200PPM, the equipment routine maintenance staff ought to be notified to function the method, otherwise the h2o and oxygen purification technique will be damaged.

3. Prior to beginning the cycle, check whether or not the cabinet is in situation or regenerating. As the over pointed out functions are in progress, it is definitely forbidden to cycle.

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

A. Prior to regeneration, make 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.
