Cole-Parmer Essentials Humidity Sponge, Regenerable; 3" X 3" bags, 40 bags/pk
Cole-Parmer Essentials Regenerable Humidity Sponge™ (pack of 40)
Humidity Sponges™ meet all drying requirements
The latest in drying technology turns any container into a desiccator. Indicator bag particles show when moisture capacity has been reached.
Nontoxic and ideal for clean rooms
Humidity Sponges™ meet FDA (Food and Drug Administration) requirements for use in direct contact with food and drugs. Desiccant (sodium calcium aluminosilicate hydrate) is nontoxic and is a GRAS (Generally Recognized as Safe) material. It is ideal for storing food/pharmaceutical samples, electronics, PC boards, optics, chemicals, and equipment. Outer material is made of DuPont’s Tyvek* breathable, high-density polyethylene. Zero-Dust bags are certified as Class M3.5 (formerly Class 100) clean room compatible.
Retains 16% moisture, guaranteed
Drying capability depends on volume, temperature, and moisture. As a benchmark, one bag will maintain dry conditions in a container with a volume of two gallons (476 cubic inches/7800 cubic centimeters). Bags are guaranteed to retain 16% moisture by weight; typical results are 37% moisture absorption. Each bag measures 3 x 3 x 1/4 inches and weight is 3/8 ounce.
Indicator Humidity Sponges™
Indicator Sponge has one side of clear film and one of white Tyvek*. It contains blues particles which turn pink when the desiccant has reached its moisture capacity and needs to be replaced. Indicator Humidity Sponge™ cannot be regenerated.
