Open the packing box and first check whether the joints on the vacuum glove box are loose during transportation. For example, if there is any looseness, please tighten the corresponding screws, and then try to vacuum. 1. The method of vacuuming and inflating: 1. This product is divided into two parts: the main box and the transition chamber. The main box must not be evacuated alone, and the transition chamber can also be evacuated alone. 2. 2. Open the door inside the transition chamber first, and then close all the glove interface glands, valves and doors outside the transition chamber. 3. Open the three-way valve between the glove ports (rotate counterclockwise), and connect the space between the glove interface gland and the glove to the box body, so that the inside and outside of the glove (box and interface) are pumped out during pumping. Vacuum, keep the pressure balance on both sides. 4. Connect the vacuum pump to a valve in the transition chamber, turn on the vacuum pump, and slowly open this valve to pump air to the system (for example, the speed of opening the valve is very fast, which may cause gloves to expand). 5. When the pointer of the vacuum gauge drops and stabilizes at -0.1MPa, the vacuum is completed. At this time, the valve should be closed first and the vacuum pump should be closed again. 6. Then fill the box with inert gas through another valve until the pressure is slightly higher than the atmospheric pressure (barometer index is 0MPa), so that the pressure inside and outside the box is basically balanced, and the inside is slightly higher than the outside, which can ensure the atmosphere It will never infiltrate the inside of the box (if you want to make the gas in the box more and more pure, it is very good to repeat the above extraction and inflation process several times). Turn off the three-way valve connected to the glove interface, open the gland on the glove interface, and you can operate. 2. How to put objects in and out of the main box of the glove box: 1. How to put the objects in the main box: After you have completed the above “(1) Vacuum and inflate” operations, for example, you need to put the objects in To enter the main box, please close the inner door of the transition room first, open the outer door of the transition room, put the objects in, and then close the outer door, and use the two valves on the transition room to exhaust and inflate. The pressure and atmospheric pressure in the main box and the transition chamber must be basically balanced, so that the door inside can be opened and the objects can be taken into the main box. 2. How to take out the objects in the main box: Put the objects in the transition room first, and close the transition room door tightly. If the transition indoor air pressure and atmospheric pressure are basically balanced, the transition outdoor door can be opened to take out the object.
What are the uses of the glove box? In the process of scientific experiments, some substances are easily oxidized and deliquescent in the atmosphere, which makes the chemical reaction of the test substance and the pre-treatment of the sample very difficult, which affects the test process and test results. The vacuum glove box (also known as the vacuum inert gas operation box) effectively solves these problems. The device can safely put in and take out the test samples, and operate, react and test freely in an oxygen-free and water-free state to ensure The normal conduct of scientific experiments. This product is an ideal device for scientific experiments in universities, research institutes, and enterprise laboratories. It is widely used in biochemistry, metallurgy, electronics, chemical engineering, geology, minerals, medicine and other departments.
The glove box is laboratory equipment that fills the box with high-purity inert gas and circulates and filters out the active substances in it. Also called vacuum glove box, inert gas protection box, etc.
The main function of the glove box is to remove O2, H2O, and organic gases. It is widely used in ultra-pure environments without water, oxygen and dust, such as: lithium-ion batteries and materials, semiconductors, super capacitors, special lamps, laser welding, brazing, material synthesis, OLED, MOCVD, etc. It also includes biological applications, such as anaerobic bacteria culture, cell hypoxia culture, etc.
