Glove box purging:

(After opening the purging, the inlet pressure can be appropriately reduced)

1) Definition: Replace the gas in the chamber with working gas, and the gas in the chamber is discharged from the purging valve on the top of the glove box.

2) Purging steps:

①Ensure sufficient working gas;

②Close the loop;

③Open purging;

④Adjust the auxiliary gauge of the pressure reducing valve and set the pressure to 0.1-0.2Mpa

3) Reasons for purging:

①First debugging;

②Not activated for a long time;

③Incorrect operation, causing air to enter;

④Remove organic solvents, acid-base solvents and other substances harmful to the glove box in the box (excessive content of organic solvents will affect the normal operation of the oxygen probe and the circulation system).

Glove box water probe cleaning (only for washable probes)

one) Explanation: If the h2o probe is not cleaned for a prolonged time, some grime will adhere to the area, influencing the detection.

two) Steps:

① Close the cycle and analyzer

② Established the operating stress to +5 to + 8mbar

③Remove the water probe and quickly blind the air outlet with a blind plate

④Unscrew the metallic protective protect on the entrance of the probe, wash it with deionized water, and then dry it with dust-cost-free paper, then moisten the probe with dust-totally free paper dripped with cleansing fluid, and use evenly

⑤ Place it back again in place, open the cycle, switch on the analyzer after 1 hour, and return to normal stage after 50 percent an hour.

notice:

After the drinking water probe is cleaned, the glove box strain is established to the unique value, and the cycle is turned on but the analyzer is turned on yet again after one hour, simply because after the drinking water probe is cleaned, the probe floor is cleaned with deionized drinking water or sixty five% concentrated phosphoric acid wetting consists of h2o Sure, if the analyzer is turned on prematurely, the h2o benefit will always be detected and exhibited to exceed the normal, so it is essential to circulate in the tank for a while and hold out for the h2o vapor to dissipate ahead of turning it on once more.

Required auxiliary equipment and accessories: vacuum pump (2L), nitrogen (inert gas such as argon), connecting pipe

1. Place the vacuum glove box on the test bench in a balanced manner, power on the inspection window, and turn on the front lighting.

2. Open the glove hole gland, open the door inside the transition chamber, and then close all the glove interface glands, valves and doors outside the transition room.

3. Open the three-way valve between the glove ports (rotate counterclockwise), connect the space between the glove interface gland and the glove to the box, so that the inside and outside of the glove (box and interface) are simultaneously evacuated and maintained The air pressure is balanced on both sides.

4. Connect the vacuum pump to a valve in the transition chamber (or any valve on the main box) through the vacuum connecting pipe, turn on the vacuum pump, slowly open this valve, and pump air to the box (if the valve is opened too fast, it may Cause gloves to swell).

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 then the vacuum pump.

6. Then fill the box with inert gas through another valve until the air pressure is 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 (not easy to be too high). Ensure that the atmosphere does not penetrate into the inside of the box (if you want to make the gas in the box more pure, it is best 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. (When opening the glove hole cover, make sure that the pressure inside and outside the box is balanced, otherwise the gloves will expand outwards)

Remark:

1. If the joint of the vacuum pump is different from that of the glove box, the joint of the vacuum pump can be replaced, or there are two connecting pipes with different specifications in the middle to connect with a conversion joint.

2. The connection method of the inert gas source bottle and the vacuum pump is the same. If the joints do not match, they need to be converted.

The installation environment of the vacuum glove box:

To

Electricity: 220V/50Hz is required;

To

Water: It is necessary to connect ordinary tap water to the cooling water inlet of the purification system, and the valve does not need to be opened for a long time until the water tank is full;

To

Gas: It is necessary to provide inert gas (N2 or Ar) or mixed gas (N2 or Ar accounted for 90%, H2 accounted for 10%). If there is no such mixed gas, it can be replaced by a pure gas of N2 or Ar and H2.

We know that 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 Vacuum inert gas operation box) effectively solves these problems. The device can safely put in and take out test samples, and operate, react and test freely in an oxygen-free and water-free state, ensuring the normal progress of scientific experiments. .

The glove box is mainly composed of two parts: the main box body and the transition chamber. If users have other special requirements, they can also be designed and manufactured according to their needs.

There are two (or more than two) glove operation interfaces on the main box body, which are distributed on the front side (or front and back sides) of the box body, which enables the operation box to be operated by one (or several) people at the same time, which improves the box body The efficiency of use. In addition, there are observation windows on the front (or front and back) of the box, so that the operator can clearly observe the operation process inside the box, so that the operation process is intuitively displayed in front of the operator.

The valve of the transition chamber has suction and charging nozzles, which can be connected when suction or charging is required. Valves and nozzles are also installed on the main box body, which can be used by users when deflating or inflating the main box body to maintain air pressure balance (the three-way valve between the glove ports can also be used to deflate if necessary). Illumination fluorescent lamps are installed above the front observation window of the main box.

The transition chamber is used as the transition space between the main box body and the outside of the box body. It is composed of two sealed doors, two valves and a chamber body. The two doors inside and outside can effectively isolate the main box from the outside, so that things inside and outside the box can enter and exit when the main box is isolated from the atmosphere, thereby avoiding the trouble of repeatedly vacuuming and inflating the main box.

Open the packing box and first check whether the joints on the glove box are loose during transportation. If there is any looseness, please tighten the corresponding screws, and then you can try to vacuum.
