The quality of the is determined by many factors, mainly leakage rate, water and oxygen index, regeneration frequency, equipment failure rate and function. 

1)Leakage rate: Leakage is the most important factor affecting the performance of the glove box, because the size of the leakage rate determines the concentration of water and oxygen impurities in the glove box, the regeneration frequency, and the life of the gas purification material. The leakage rate of a single-station glove box is usually <0.001%vol/h to 0.05%vol/h. 

2)Water and oxygen index: The water and oxygen index refers to the concentration of water and oxygen in the box, which is a standard for measuring the purity of the gas in the glove box. Usually their concentration is maintained at less than 1PPM (parts per million). When the water oxygen concentration continues to be greater than 1PPM, it indicates that the gas purification capacity of the purification column has been consumed to a considerable extent, and it has been unable to maintain the water oxygen index of the glove box within the required range. At this time, the gas purification system of the glove box needs to be regenerated. 

3)Regeneration frequency of the gas purification system: The regeneration of the glove box requires the purchase of regeneration gas, and the use of the glove box must be stopped for one day during regeneration. Therefore, excessive frequent regeneration not only increases operating costs, but also affects production efficiency. The frequency of regeneration of the gas purification system is usually 1 to 12 times a year.

4)Equipment failure rate: Failure rate is a very important indicator of the quality of the glove box. The main faults of the glove box occurred in the water and oxygen analyzer, valves, and circulating fans. 

5) Function: Although the main function of the glove box is to provide a water-free and oxygen-free environment, many functions can make the use more convenient and efficient, and can also avoid damage to the equipment or the atmosphere in the glove box.  

ACEY NEW ENERGY is specialized in providing lab equipment(coating machine, roll press machine, 8-cahnnels tester) for lithium battery research, glove box is necessary too. The glove box provides a high purity and clean space for lithium battery research.
