Silica Gel Self Indicator Coarse Extra Pure is a high-quality granular silica gel desiccant with embedded moisture indicator properties. It appears as blue beads that turn pink upon moisture saturation, enabling easy visual detection of adsorbed water. Widely used in laboratories and industry, it protects sensitive equipment, gases, and packaged goods from humidity damage. Its coarse granular form ensures efficient air flow and rapid moisture adsorption, making it essential in moisture-sensitive environments such as compressed air systems, gas dryers, and protective packaging.
