Application and Evaluation Criteria of Vacuum Glove Boxes

The vacuum glove box serves as a universal work platform providing a high-purity inert gas environment. This platform can achieve very high concentrations of inert gases. Certain material research processes or experiments, which are highly sensitive to water or oxygen, can be conducted within the vacuum glove box.

The primary assessment criteria for the automatic vacuum glove box are:

1. Vacuum Degree: Only when a certain vacuum degree is reached can the atmosphere inside the box meet the requirements.

2. Preservation Time: The chamber's sealing performance meets requirements only when a certain vacuum degree and negative pressure state are achieved and maintained for a specific duration.

3. The use of compact transition chambers facilitates quick and convenient access to small samples, ensuring a controlled working environment in the lab. This not only saves protective atmosphere and operational time but also has led to the widespread application of vacuum glove boxes in various industries and fields, including scientific experiments, new material research and development, biomedicine, chemicals, lithium batteries, solar cells, nuclear materials and nuclear industry, new lighting, and special welding vacuum coating.
