3A Molecular Sieve Mesh, Beaded

CHEMICAL FORMULA K12 [(Al02)12(SiO2)12] · nH2O

mSORB 3A molecular sieve is a multiple purpose, highly porous, high capacity alkali metal alumino-silicate in the spherical form. It is the potassium form of the Type A crystal structure with pore diameters of approximately 3Å. The 3Å pore opening will allow moisture to be adsorbed but will exclude unsaturated hydrocarbons and highly polar alcohols such as methanol and ethanol. It has high mass transfer efficiency and durability.
