Product Category Description:

Humidity sponges turn any container into a desiccator. Ideal for storing samples, food, pharmaceuticals, electronics, PC boards, optics, diagnostics, museum pieces, chemicals, instruments, and documents. Humidity sponges meet FDA requirements for use in direct contact with food and drugs. Sodium calcium aluminosilicate hydrate desiccant is nontoxic and is a GRAS (Generally Recognized as Safe) material. Desiccant is guaranteed to absorb approximately 16% of its weight in water. It will typically absorb approximately 37% of its weight in water, depending on relative humidity. Each bag is 7.6x7.6x0.6cm (3x3x1/4") and weighs 10g (0.35oz.).

The indicating, nonregenerable humidity sponge has white Tyvek® on one side and clear polyethylene film on the other side. This desiccator contains cobaltous chloride indicator which changes from blue to pink upon moisture absorption. When the indicator turns pink, the desiccator needs to be replaced.

The nonindicating, regenerable humidity sponge has white Tyvek on both sides. This desiccator contains a relative humidity card that changes from blue to pink to show when the bags need to be regenerated. The indicator for the relative humidity card is cobaltous chloride.
