Precautions when operating the Nichwell glove box

glove box manufacturers usa,glove box manufacturers is broadly utilised in industries with high specifications for gas purification. Despite the fact that the recent glove box layout is much more affordable and straightforward to operate. Even so, the composition within the glove box is complicated, there are numerous important components, and the procedure is marginally improper, which may possibly lead to loss to your experimental final results. This write-up introduces you how to appropriately use the vacuum glove box, and the precautions when novices work the glove box.


1. Work just before procedure:


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


two. Verify whether or not the vacuum pump is turned on typically.


3. Verify no matter whether the circulation in the glove box is open up. (Purification column-I or purification column-II should open up one of them)


four. Check the upper restrict force in the location should be +one, the lower restrict strain is


5. Verify no matter whether oxygen and dew stage are normal (oxygen is underneath .1ppm, dew point is above -40)


6. The vacuum pump of the more than-bin ought to be in the typically open up point out

two. Procedure notes:


1. The vacuum pump ought to be held on for the duration of method procedure.


2. When the oxygen focus in the tank exceeds 200PPM, the tools routine maintenance personnel ought to be notified to work the technique, or else the h2o and oxygen purification program will be destroyed.


three. Before starting up the cycle, check out no matter whether the cupboard is in situation or regenerating. As the over described operations are in development, it is completely forbidden to cycle.


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


A. Prior to regeneration, make sure that the glove box has been cleaned with inert fuel (H2O &lt;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.
