These humidity sponges turn any container into a desiccator. The sodium calcium aluminosilicate hydrate desiccant is nontoxic and ideal for storing samples, foods, pharmaceuticals, etc. Certified as Class 100 Cleanroom compatible. Guaranteed to retain 16% moisture by weight, but typical results are 37% moisture absorption. Each sponge measures 3 x 3 x 1/4 in. and weighs 10 g.
Indicator desiccant contains a blue indicating gel that turns pink when the pack has achieved its moisture capacity and needs to be replaced. It cannot be regenerated. The Regenerable desiccant may be regenerated at 220°F and reused continuously but does not have a colour indicator. Each package has a relative humidity card which changes from blue to pink when bags are no longer active and need regeneration.
