Vacuum glove box is commonly utilised in industries with substantial requirements for gasoline purification. Despite the fact that the present-day glove box design is far more fair and straightforward to run. However, the construction within the glove box is difficult, there are numerous important areas, and the operation is somewhat improper, which could induce loss to your experimental results. This post introduces you how to accurately use the vacuum lab glove box box, and the safety measures when novices run the glove box.













A person. Operate ahead of procedure:













one. Look at if there is nitrogen in the nitrogen bottle. The nitrogen need to be changed in time. The output stress of nitrogen is set to .4mpa.













two. Check out no matter whether the vacuum pump is turned on commonly.













3. Look at no matter if the circulation in the glove box is open up. (Purification column-I or purification column-II need to open a single of them)













four. Test the upper restrict force in the location should be +one, the reduced restrict force is













five. Verify regardless of whether oxygen and dew stage are ordinary (oxygen is under .1ppm, dew level is above -forty)













six. The vacuum pump of the about-bin should really be in the ordinarily open up state













two. Operation notes:













one. The vacuum pump must be retained on throughout technique procedure.













two. When the oxygen focus in the tank exceeds 200PPM, the devices upkeep personnel must be notified to run the method, usually the drinking water and oxygen purification process will be weakened.













three. Right before commencing the cycle, test irrespective of whether the cabinet is in situation or regenerating. As the over pointed out operations are in progress, it is completely forbidden to cycle.













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













A. Ahead of regeneration, assure 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.
