Blue Indicating Silica Gel

sSORB® type-A indicating blue silica gel, made of the naturally occurring mineral silicon dioxide, has been purified and processed into hard, smooth beads. These beads are then 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 and becomes saturated.

Chemical Formula:  SiO2 · nH2O + CoCl2

Blue Indicating Silica Gel Typical Applications

Blue indicating silica gel is frequently used with:

Due to the addition of the moisture indicator, sSORB® Blue Silica Gel should not be used in contact with products intended for consumption such as food or pharmaceuticals.

Blue indicating silica gel’s high specific surface area (around 800 m2/g) allows it to adsorb water readily, making it useful as a desiccant (drying agent). Silica gel is often described as “absorbing” moisture, which may be appropriate when the gel’s microscopic structure is ignored, as in silica gel packs or other products. However, material silica gel removes moisture by adsorption onto the surface of its numerous pores rather than by absorption into the bulk of the gel.

Storage

Store aSORB® blue silica gel in a dry location to prevent unintentional water adsorption. Reseal packages after opening to prevent contamination and unintended water adsorption. We recommend that you rotate stock so oldest material is used first.
