Anhydrous calcium sulfate with cobaltous chloride indicator
Anhydrous calcium sulfate with cobaltous chloride indicator.
An efficient drying agent giving visual indication of the progress
of absorption and exhaustion.
Will absorb 6-10% of its weight in water, depending on relative

rose-red. Regeneration is accomplished by heating (layered 1 granule deep), for
1 hour at 120°C.
