Use in desiccator cabinets, non-vacuum desiccators, analytical balance cases, and precision laboratory instruments. Cartridges contain silica gel desiccant with cobaltous chloride indicator. Transparent polystyrene dish allows visual inspection of color change from blue to pale pink with moisture absorption. A porous membrane covers the dish of desiccant, providing good moisture absorption while preventing desiccant spillage.
Blue color is regenerated by heating cartridges at 50°C (122°F) overnight. For more rapid drying, cut the membrane and transfer the silica gel crystals into a glass or porcelain dish. Heat at 150°C (302°F) for one hour. Dispose of cartridge after repeated use.
