Ultra-low oxygen and ultra-low moisture inert atmosphere is the core foundation of vacuum glove box application, especially for lithium battery research, semiconductor packaging, metal organic synthesis, and aerospace material testing. A large number of users encounter the problem of unstable internal atmosphere purity in the use of ordinary glove boxes: oxygen and water content fluctuate frequently, local high-pollution dead zones exist in the box, and the purification system fails to work effectively after long-term use, leading to frequent experimental failure.
The main reasons for unstable atmosphere purity are summarized as follows. First, the purification system of ordinary equipment is simple, with single catalyst and low adsorption capacity. After long-term circulation, the catalyst and zeolite adsorption materials are saturated and fail to regenerate completely, resulting in decreased oxygen and water removal efficiency. Second, unreasonable internal air duct design leads to uneven gas circulation, forming dead zones where moisture and oxygen cannot be discharged in time, even if the display data is normal, the actual local atmosphere does not meet the standard. Third, improper material transfer operation of the front cabin and incomplete evacuation cycle will cause instantaneous moisture and oxygen surge, breaking the stable state of the internal atmosphere.
Atmosphere purity failure is the primary killer of precision experiments. Trace oxygen will oxidize active metal materials and battery electrodes, while trace moisture will cause hydrolysis reaction of chemical reagents and material deliquescence. In scientific research, unstable purity leads to inconsistent experimental data and poor repeatability, affecting research progress and paper output. In industrial production, it will cause product performance degradation, short service life, and batch quality differences, bringing huge economic losses to enterprises.
Our high-purity vacuum glove box is specially optimized for atmosphere purification and circulation systems to solve all purity instability problems. The equipment is equipped with a high-efficiency dual purification system, using imported Q5 catalyst and high-density zeolite adsorption materials, which can efficiently remove oxygen and moisture in the inert gas. The intelligent regeneration system realizes automatic timing and quantitative regeneration of purification materials, completely avoiding adsorption saturation failure, and maintaining long-term stable purification capacity.
In terms of gas circulation, we adopt a full-box uniform air duct circulation design with no dead zones in the working area. The high-power circulating fan ensures real-time uniform mixing of internal gas, so that oxygen and water content of each position in the box is consistent and stable. The system supports real-time high-precision monitoring of oxygen and moisture content, with data accurate to 0.1ppm, realizing visual atmosphere management. For the material transfer link, the front cabin is equipped with an intelligent automatic evacuation cycle system, which standardizes the transfer process, avoids manual operation errors, and effectively prevents external air from infiltrating into the main box.
After strict testing, our glove box can stably control the internal oxygen content below 1ppm and moisture content below 0.5ppm, realizing long-term ultra-high purity inert environment. It completely solves the problems of purity fluctuation and local pollution, ensures 100% repeatability of experimental data and stable batch production quality, and is widely recognized by scientific research institutions and new energy manufacturing enterprises worldwide.
