General description
Silica gel with the indicator or orange gel frequently used as a drying agent in laboratories is suitable for drying all gases and solids. It is used in drying towers, desiccators, and absorption tubes. Due to its vast surface area, silica gel orange provides excellent absorption capacity, enabling longer storage conditions. When it absorbs moisture, it also turns orange to colorless. (approx. 6 wt % load).
