Tokyo Glass Kikai (TGK) Charcoal Silica Gel Tubes

Activated carbon has excellent adsorption power for many types of organic solvent vapors, but it is not suitable for collecting polar substances such as methanol. Silica gel, on the other hand, is effective in collecting polar substances. Therefore, we prepared a collection tube filled with both activated carbon and silica gel. This tube can be used to collect polar and non-polar solvents at the same time.
4 layers are filled with 20-40 mesh activated carbon 50/100 mg and 20-40 mesh silica gel 300/600 mg.
