Installation and Maintenance of Glove Box Gloves

Please refer to the following figure for the first installation of the glove box. Put the glove on the glove port first, and then install the inner and outer seal rings separately. After installation, check to make sure that the seal rings are in the grooves.

   If the gloves are damaged during use, they should be replaced in time. The steps are as following:

1. Push the glove to be replaced down into the glove box;

2. Remove the outer O-ring and move the inner O-ring to the outer groove of the glove port;

3. Roll the glove to the outside of the O-ring, taking care not to let the glove fall from the port of the glove;

4. Compress new gloves as much as possible to expel the air inside;

5. Install the new glove on the glove port and put it on the old glove;

6. Install an O-ring on the outside of the new glove and the groove inside the glove port;

7. If possible, put the new gloves into the isolated working gas environment for cleaning (this will remove the air to the greatest extent and reduce the amount of air entering the glove box);

8. From inside the glove box, use another glove to take the old glove into the box;

9. Install an O-ring on the groove outside the glove port outside the new glove;

10. Take out the old gloves through the transition chamber and dispose of them properly.

Glove Box Operation Tips

Operation tips

1. Regardless of whether you open the inner door or the outer door, you must ensure that the air pressure on both sides of the door is basically balanced, otherwise, either it will not open, or a "gas explosion" phenomenon occurs. Similarly, when pumping and inflating the box, it is also necessary to ensure that the three-way valve is open (that is, the air pressure inside and outside the glove is equal), otherwise, the glove will expand and burst.

2. If there is air leakage in the chamber, please first check whether the door of the transition room is tightly closed and whether the glove mouth is damaged. If there is leakage, please check the vacuum meter seat, valve and "O" ring and vacuum rubber on the two doors. The "O" ring on the transition room door and the glove door should be replaced regularly (depending on the frequency of use by the user).

3. When pumping down the system, please slowly open the valve and pay attention to the change of gloves at any time. If expansion occurs, the pumping speed should be slowed down. If the problem cannot be solved, the pumping should be stopped. If the gloves burst, check three. Whether the valve is open.
