In order to prevent the impact of organic solvents on the purification column, a solvent column is connected in series to the Glovebox system, which can effectively remove the solvent volatilized from the system. The medium is mainly high-quality and efficient activated carbon. The organic solvent adsorption system is filled with high-efficiency activated carbon and Activated alumina that have been washed and dried. The filling volume is 7KG, which is installed at the bottom of the box. There are KF40 interfaces at the top and bottom of the column, which is convenient for refueling. Users can change materials by themselves.
