13X Molecular Sieve 4x8 Mesh, Beaded

Revised 2015

CHEMICAL FORMULA Na86[(AlO2)86(SiO2)106] • nH2O

PRODUCT DESCRIPTION DelSORB® 13X48B molecular sieve is a multiple purpose, highly porous, high capacity alkali metal alumino- silicate in the spherical form. It is the sodium form of the Type X crystal structure with pore diameters of approximately 10Å. It can adsorb all molecules that can be adsorbed by 3A, 4A, and 5A molecular sieve. Type 13X can also adsorb molecules such as aromatics and branched-chain hydrocarbons, which have large critical diameters.
