Precautions when functioning the Nichwell glove box
Vacuum glove box is broadly utilised in industries with high specifications for gas purification. Though the existing glove box style is much more realistic and simple to run. However, the framework inside of the glove box is challenging, there are a lot of essential components, and the operation is marginally incorrect, which may possibly result in loss to your experimental final results. This report introduces you how to correctly use the vacuum glove box, and the safeguards when novices run the glove box.
One. Operate prior to procedure:
1. Check out if there is nitrogen in the nitrogen bottle. The nitrogen need to be replaced in time. The output strain of nitrogen is established to .4mpa.
two. Examine whether or not the vacuum pump is turned on usually.
three. Check no matter whether the circulation in the glove box is open up. (Purification column-I or purification column-II should open a single of them)
4. Verify the upper limit pressure in the environment should be +one, the reduced limit strain is
5. Check out whether oxygen and dew level are standard (oxygen is underneath .1ppm, dew stage is earlier mentioned -40)
6. The vacuum pump of the above-bin should be in the usually open up state
two. Operation notes:
1. The vacuum pump need to be stored on for the duration of system operation.
2. When the oxygen focus in the tank exceeds 200PPM, the tools upkeep staff need to be notified to function the technique, or else the h2o and oxygen purification program will be broken.
3. Just before beginning glove box price , check out whether the cabinet is in condition or regenerating. As the previously mentioned talked about functions are in progress, it is definitely forbidden to cycle.
4 .Two purification columns are not able to be regenerated at the same time.
A. Before 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.
