A The likelihood of a vacuum glove box maintaining a vacuum state for over a decade is low. The vacuuming time of a vacuum glove box is usually affected by various factors such as model, specifications, operating environment, and usage conditions, and is generally between 30 minutes and 2 hours. In addition, the sealing and maintenance status of the vacuum glove box, as well as the performance and lifespan of the vacuum pump, can also affect its vacuum holding time. In long-term use, the glove box may experience a decrease in vacuum due to aging seals, gas leaks, and other issues. Therefore, to ensure the stability of the experimental environment and the accuracy of the experimental results, it is necessary to regularly maintain and upkeep the vacuum glove box.

A If the supply of regeneration gas is interrupted during the glove box regeneration process, the regeneration operation should be immediately stopped to prevent the purification material from being damaged due to a lack of necessary gas. Firstly, check for any leaks or insufficient pressure in the gas supply system and promptly resolve these issues to restore gas supply. If the gas supply cannot be quickly restored, follow the instructions in the operating manual to safely close the glove box and take appropriate protective measures; If leakage and other issues are ruled out, replacing the bottle and getting angry again will allow for continued regeneration; The glove box regeneration allows for a short period of power outage, and within 30 minutes, the regeneration process will automatically resume when powered on again. During the processing, it is essential to follow safety operating procedures to avoid potential safety risks caused by gas interruption.

A It is generally not recommended to leave the glove box without a transition compartment. The function of the transition compartment is to serve as a channel for transferring items in or out of the glove box. If a transition compartment is not added, the glove box window needs to be opened to operate when transferring items in or out. This will disrupt the stable atmosphere inside the glove box and affect the experimental results. Each time items are transferred in or out, a new cleaning operation must be performed. When transferring items, the transition compartment of the glove box can perform vacuum and inflation operations on the space inside the transition compartment, keeping the atmosphere inside the transition compartment consistent with the atmosphere inside the glove box. When transferring items in or out, it is not only convenient, but also does not affect the stable atmosphere inside the glove box.

A Vacuum coated glove boxes are widely used in optics, electronics, sensitive material processing, nuclear industry, biomedical and new material research and development. In the field of optics, it is used for the manufacturing of high-precision optical components such as lenses, optical filters, and reflectors; In the field of electronics, it assists in the preparation of devices such as OLEDs and semiconductors, and also plays a role in the field of new energy such as solar cells; In terms of sensitive material processing, it provides a high-purity environment for semiconductor materials, lithium battery electrode materials, etc; In the nuclear industry and toxic substance handling, it is an important equipment for safety protection; In the biomedical field, it ensures the accuracy and reliability of cell culture and biological sample processing.

A The glove box and vapor deposition system play a crucial role in the preparation process of perovskite solar cells. Thin film evaporation is completed in a high vacuum evaporation chamber, and sample storage, preparation, and post evaporation sample testing are carried out in a high-purity inert gas atmosphere in a glove box to ensure the purity and consistency of the coating process, thereby improving battery conversion efficiency. At the same time, during battery packaging and testing, glove boxes can protect devices from external pollution and oxidation, improve the reliability and service life of photovoltaic cells, provide a safe and reliable environment for the battery during testing, and avoid performance degradation or damage caused by exposure to air or moisture.

A The glove box provides a pure and pollution-free sealed inert atmosphere environment for grinding, screening, dissolution and other operations in geological sample preparation, ensuring sample purity, such as preventing external impurities from contaminating during the preparation of lunar soil samples. In the observation of the microstructure of geological samples, stable environment integrated electron microscopes and other instruments are provided to accurately observe the detailed characteristics of the samples, such as observing magnetite particles in lunar soil.

A Glove boxes can be used to store geological samples. Through a closed circulation system and purification system, an inert atmosphere free of water and oxygen is maintained inside the box. Good sealing can prevent the samples from reacting with external oxygen and moisture. So in the preservation of geological samples, it can effectively prevent precious and sensitive samples such as lunar soil from being contaminated and deteriorated, and maintain their original state; The low oxygen and low humidity environment provided can slow down the rate of chemical reactions, reduce the risk of sample decomposition, and achieve long-term storage; It can also integrate identification systems and recording devices to facilitate sample identification, recording, and future identification and query.

A In the regeneration process of the glove box, the role of hydrogen is to reduce the copper catalyst, restore its activity, and effectively remove oxygen from the box. Hydrogen is mixed with working gases such as nitrogen, argon, or helium, with the proportion of hydrogen controlled at 5-10%, because this ratio can ensure sufficient reducing ability and avoid safety risks caused by high hydrogen concentration. Hydrogen is a flammable and explosive gas, and high concentration can increase safety hazards, which may lead to the risk of fire or explosion. Moreover, a high proportion may not necessarily improve purification efficiency, but may waste resources and increase unnecessary energy consumption.
