Blue Silica Gel

sSORB® blue silica gel is ideal as a primary desiccant or blended with other desiccants in any application where visual control of moisture is required. sSORB silica gel beads are saturated with a moisture indicating solution that gives them a deep blue color when dry. The color changes from blue to purple to pink as it adsorbs moisture.

Chemical Formula: SiO2 · nH2O + CoCl2
