sSORB™
TYPE-A BLUE INDICATING SILICA GEL BEADED
Our sSORB™ Type-A Blue Indicating Silica Gels are naturally occurring mineral silicon dioxides that have been purified and processed into a hard, smooth beaded form. The beads are then saturated with a moisture indicating solution that gives them a deep blue color when dry. It is also known as a narrow pore silica gel and has a vast network of interconnecting pores with diameters of 20-30Å. These pores have a strong affinity for moisture and use physical adsorption and capillary condensation to trap and hold it. Silica gel will remove moisture at temperatures as high as 220°F, but is best used at room temperature (70-90°F) and high relative humidity (60-90% rh). The color changes from blue to purple to pink as it adsorbs moisture.

TYPICAL APPLICATIONS
- As a primary desiccant or blended with other desiccants in any application where visual control of moisture is required, such as compressed air dryers, gas drying, breathers, for protection of non consumable packaged goods, drying and storage of flowers and seeds, etc. Due to the addition of the moisture indicator, sSORB™ AB25B Type-a Blue Indicating Silica Gel should not be used in contact with products intended for consumption such as food or pharmaceuticals.

HANDLING & STORAGE RECOMMENDATIONS
Store sSORB™ type-a blue indicating silica gel in a dry location to prevent premature 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.
