13X Molecular Sieve 4 x 8 Mesh 500g Poly Jar

13X Molecular Sieve has a pore size of roughly 10A. This is considerably larger than any of the A type openings. This desiccant is used primarily for refinements of liquid and gases because it offers synchronized absorption for bi-molecule and tri-molecule. It can co-adsorb CO2 and H2O, H2O and H2S.
