Anaerobic glove box is divided into four parts: anaerobic chamber, transmission cabin, bare hand sleeve operation hole, gas circuit and circuit control system.

　 1. Anaerobic room

　　Internal cavity mechanical forced convection and internal cavity positive pressure, to achieve constant temperature, humidity control, deoxygenation, biological detoxification, the four states are not uniform, and rapid recovery, operation and cultivation are carried out in the same room.

　　 2. Transmission module:

　　Using a compact cylindrical design, it is easy to transfer samples with one person and one hand.

　　 3. Bare hand sleeve operation hole:

　　 No need for vacuum/nitrogen replacement process, both hands can go straight in and out of the anaerobic cavity.

　　 4. Control system:

　　Timely state self-check alarm function to ensure the normal operation of the equipment.

As a kind of precision equipment, the principle of glove box is as follows:

Glove box system is a laboratory equipment that fills high-purity inert gas into a sealed box and circulates and filters out the active substances (water and oxygen can reach below 1ppm) through the purification system.

It is mainly composed of box, frame, transition cabin, gas purification system, PLC automatic control system, etc.

Mainly for the removal of O2, H2O and organic gas.

It is suitable for ultra pure environment without water, oxygen and dust. Such as: Li-ion battery and materials, semiconductor, super capacitor, special lamp, laser welding, brazing, etc.

In the case of micrana glove box, we can:

The glove box is a closed cycle design, saving operation cost. Under the standard condition, i.e. constant temperature of 20oC, a standard atmospheric pressure, 99.999% inert gas source, and the water oxygen index is less than 1 ppm;

304 stainless steel plate is used for the box body and large and small transition tanks. The front window is toughened glass, wear-resistant and corrosion-resistant;

Touch screen PLC control, high degree of automation, can achieve: automatic control of gas pressure in the box, automatic cleaning of the box atmosphere, automatic regeneration of purification materials, automatic recording of system operation data and other operations;

Users can select various accessories on the standard glove box according to the actual needs: water analyzer, oxygen analyzer, solvent adsorber, refrigerator high temperature heating device, laser welding machine, etc.

Vacuumglove box is widely used in gas purification industry. Although the present glove box design is more reasonable and easy to operate. However, the structure of the glove box is complex, there are many important parts, and the operation is a little improper, which may cause loss to your experimental results. This article introduces how to use the vacuum glove box correctly and the precautions for novices when operating the glove box.

Use of Nichwell glove box: in the process of scientific experiment, some substances are easily oxidized and deliquesced in the atmosphere, which makes the chemical reaction of test substances and the pre-treatment of samples very difficult, affecting the test process and test results.

Nichwell vacuum glove box (also known as vacuum inert gas protection box) effectively solves these problems. The device is a laboratory equipment that fills high-purity inert gas into the box and circularly filters out water, oxygen, organic gas and other substances. Its main function is to remove O2, H2O and organic gas, and it is widely used in ultra pure environment without water, oxygen and dust. The product can be applied to the research and development and production of lithium battery, physical and chemical research, powder metallurgy, nuclear technology, special welding, OLED and pled research, pharmaceutical industry, material processing, special lamp research and development and production, fine chemical industry, polymer materials and other industries.

Vacuum glove box is widely used in industries with high requirements for gas purification. Although the current glove box design is more reasonable and easy to operate. However, the structure inside the glove box is complicated, there are many important parts, and the operation is slightly improper, which may cause loss to your experimental results. This article introduces you to the precautions before operating the glove box.
Work before operating the glove box:
1. Check whether there is nitrogen in the nitrogen bottle. The nitrogen should be replaced in time. The output pressure of nitrogen is set to 0.5mpa.
2. Check whether the vacuum pump is turned on normally.
3. Check whether the circulation in the glove box is open. (Purification column-I or purification column-II should open one of them)
4. Check the upper limit pressure in the setting should be +1, the lower limit pressure is 0
5. Check whether oxygen and dew point are normal (oxygen is below 0.1ppm, dew point is above -40)
6. The vacuum pump in the over cabin should be in the normally open state

1. The vacuum pump should be kept on during glove box system operation.
2. When the oxygen concentration in the tank exceeds 200PPM, the equipment maintenance personnel should be notified to operate the system, otherwise the water and oxygen purification system will be damaged.

3. Before starting the cycle, check whether the cabinet is in condition or regenerating. As the above mentioned operations are in progress, it is absolutely forbidden to cycle.
4. The two purification columns cannot be regenerated at the same time.
A. Before regeneration, ensure 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, properly adjust the pressure of the regeneration gas, and guarantee the sufficient supply of regeneration gas in these 3 hours After 6 hours, the origin of regeneration 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 working gloves from being damaged during the operation

Use of Nichwell glove box: During the scientific experiment, some substances are easily oxidized and deliquesced in the atmosphere, which makes the chemical reaction of the test substance and the preliminary treatment of the sample very difficult, which affects the test process and test results.

High performance materials used in aerospace and medical applications, such as titanium or magnesium, tend to oxidize and become brittle in the welding process, making it difficult to weld. In addition, the dangerous gas and particulate matter produced in the welding process will cause great harm to human body.

Aiming at the problems existing in laser welding, Nichwell can provide a set of reliable solutions, so that the welding process can be completely carried out in a controllable pure inert gas sealed cabin.

Weldingglove box aims to solve the influence of humidity and impurities in the air during laser welding. The glove box has two 90 degree cubicles, the left side is the heating cabin, the right side is the transition cabin, the maximum temperature of the heating cabin is 200 ℃, the heating plate can be cooled quickly at the same time, the outside side of the cabin is the manual door, the inside door is the automatic door, the inside and outside doors are interlocked, and the glove box is cleaned by the flowmeter control, The purification system can also be connected.

In the prior art, a vacuum port is often provided on the vacuum cavity of a vacuum coating machine, which results in uneven airflow in the vacuum cavity, and atomization sputtered from the plating material or sputtering target during the coating process. 、 Ion dispersion is uneven, which greatly rigidifies the uniformity of the coating.

Provide a glove box vapor deposition all-in-one machine. This system is integrated with a vacuum coating system and a glove box system. It can complete thin film evaporation in a high vacuum evaporation chamber and perform samples in a high purity inert gas atmosphere in the glove box. Equipment use: mainly used in solar cell perovskite, OLED and PLED, semiconductor preparation and other experimental research and application.
