Grade 50 Silica Gel does not utilize Cobalt Chloride as the color change agent. Typically used for the adsorption of water vapor in gases, this product is highly suitable in dehydrators or driers where the visual indication of the desiccant status (active/saturated) is necessary. The beads remain orange while the desiccant is in the active condition and turn to green upon saturation.
