In experiments of chemical reactions and sample treatments, some substances are so sensitive to water and oxygen that they can’t be processed in atmospheric environment. Therefore, circular purification box are invented to enable the sensitive substances to react in inert gas environment without water and oxygen. The box is widely used in lithium ion batteries and materials, semiconductors, film preparation, nano materials, catalysts, super capacitors, special lamps, laser welding, brazing, titanium alloy welding, etc.
