4A Blue Indicating Molecular Sieve

CHEMICAL FORMULA Na12[(AlO2)12(SiO2)12] • nH2O +CoCL2

PRODUCT DESCRIPTION
mSORB 4A blue indicating molecular sieve desiccant is a sodium alumina silicate molecular sieve impregnated with an inorganic metal salt moisture indicator. The desiccant will perform as a 4a molecular sieve with the additional ability to visually determine when the molecular sieve reaches saturation. When active, the molecular sieve beads are blue. As the beads reach saturation, the color changes to beige, indicating that the molecular sieve has reached equilibrium capacity and is in need of replacement.
