4A Blue Indicating Molecular Sieve

Revised 2015

CHEMICAL FORMULA Na [(AlO ) (SiO ) ] • nH O+CoCl2

PRODUCT DESCRIPTION
DelSORB® 4A48BIMS 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 plus 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.
