DelSORB White Silica Gel

Silica Gel, Type A, White, 2 – 5 mm, Beaded

CHEMICAL FORMULA SiO2 · nH2O PRODUCT DESCRIPTION

DelSORB AW25B silica gel is the naturally occurring mineral silicon dioxide that has been purified and processed into a hard, smooth beaded form. 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).

HANDLING & STORAGE RECOMMENDATIONS

Store 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.
