Blue Silica Gel, BR

Blue Indicating Silica Gel Desiccant

it is Blue Indicating Silica Gel, it contains cobalt chloride which allows the blue silica gel changes its color to pink when it reached the max adsorption capacity. When it is reactviated with heat to dry our the moisture, the pink color will trun to blue again, blue silical gel is for industrial use, do not use blue silica gel for food as the cobalt chloride is poisonous material.

BR enables users to visually confirm when the desiccant is needs to be replaced or regenerated.
