More convenient desiccant monitoring
Indicating Silica gel
Individually sealed in aluminum foil
For use with desiccator cabinets or non-vacuum desiccators, with analytical balances or precision laboratory instruments. Clear polystyrene dish allows instant visual inspection of silica gel which changes in color from blue to pale pink as it absorbs water. A highly porous membrane covers the dish of desiccant, providing excellent moisture absorbtion. Cartridges may be regenerated by heating overnight in a 50°C (122°F) oven. Silica gel is non-toxic, inert and non-corrosive.
