5A Molecular Sieve

5A molecular sieve products sold at Interra Global are alkali metal aluminosilicates in the spherical form. They are the calcium form of the Type-A crystal structure with an effective pore opening of 5A. Molecules with effective diameters greater than 5A, such as, iso compounds and all 4-carbon rings will not be adsorbed. Adsorbed molecules include NC4H10, nC4H10, C3H8 to C22H46, and Freon 12 (dichlorodifluoromethane).

Chemical Formula: Ca4,5 [(AlO2)12(SiO2)12] · nH2O

Additional information


Store 5A molecular sieve in a dry location to prevent premature water adsorption. Do not store super sacks outside; ultraviolet radiation and other adverse conditions will negatively impact its integrity and may eventually cause the bag to fail. Reseal packages after opening to prevent contamination and unintended water adsorption. We recommend that you rotate stock so the oldest material is used first.
