Standard glove box how to define the standard?

Standard, what is the data, is the requirement is more a basic guarantee of experimental safety glove box as a fully enclosed chamber, the chamber inside and outside the environment completely isolated from the chamber side of the installation of windows and gloves operators through the gloves of the material in the chamber for the operation of the glove box for a number of purposes: 1, when the operation of toxic and hazardous materials, the glove box can protect the operator and the environment; 2, when the Atmospheric substances such as bacteria and dust will contaminate the material, the glove box can be used to isolate the material outside the box, to protect the material inside the box from contamination; 3, when the air will act with the material to affect the performance of the material, the glove box will be filled with inert gas, the box is used to isolate the box outside the air, to protect the material inside the box from the air of the gas, such as water, oxygen, and sometimes even nitrogen contamination.
Inert gas glove box is roughly divided into three kinds: 1, vacuum glove box: before the operation, the entire box vacuum, the box completely pumped off the air, and then filled with high-purity gas can be used. Advantages: cheap equipment. Disadvantages: high content of water and oxygen impurities, usually more than 100PPM. 2, cleaning the glove box: the glove box for continuous nitrogen, uninterrupted leakage into the glove box gas impurities cleaning out of the glove box. Advantages: cheap equipment. Disadvantages: high operating costs, the need to consume a lot of inert gas. Water and oxygen impurity content is usually more than 10PPM. 3, the cycle of the glove box: glove box with gas purification gas, the gas inside the glove box uninterruptedly circulating through the gas purification system to remove water and oxygen and organic solvents impurities. Advantages: low operating costs, low water and oxygen content, usually less than 1PPM; with PLC and touch screen, more functions. Disadvantages: equipment prices are high. Here the above third inert gas circulation glove box referred to as the glove box glove box working gas in the box and the purification column (water-oxygen adsorber) between the PLC control and monitoring through the pipeline, circulating fans, etc. for closed circulation. When the working gas circulates through the purification column, the water and oxygen contained therein are adsorbed and then returned to the box, and as the circulation time goes by, the water and oxygen content in the working gas in the box will be gradually reduced to reach the target of less than 1ppm. The purification column will be adsorbed and saturated after a certain time cycle, and can be regenerated and reused.

Standard glove box, the main function lies in the removal of O2, H2O, organic gases. Widely used in water-free, oxygen-free, dust-free ultra-pure environment: such as lithium-ion batteries and materials, semiconductors, supercapacitors, special lamps, laser welding, brazing, materials synthesis, OLED, MOCVD, etc., but also biological applications, such as anaerobic bacteria cultures, cell culture, etc. low oxygen. The standard glove box, in addition to the above basic functions can be based on the choice of different users, to provide the size of different size options and even special needs of the internal environment, such as a glove box dedicated to laser welding standard glove box size of a lot of 1200/1500/1800/2400 or mainly for your experiments to screen the glove box standardization to meet the needs of your experimental safety! Of course, if you want to use more functions, then customize a glove box~!
