Humidity Sponge™ Regenerable/Indicator Complete
Description
The latest in drying technology turns any container into a
desiccator. Two unique Humidity Sponges™ meet all drying requirements.
Indicator bag’s gel shows when moisture capacity has
been reached
Window bag has one side of clear film and one of white Tyvek*. It
contains a blue indicating gel, which turns pink when the desiccant has
reached its moisture capacity and needs to be replaced. It cannot be
regenerated.
Regenerable bag can be regenerated and reused
continuously
Regenerable bag has white Tyvek* on both sides, and may be regenerated
and reused continuously. Regeneration requires heating in an oven at
220°F. Included in each pack is a Relative Humidity Card, which
changes from blue to pink to show when the bags need to be regenerated.
Nontoxic and ideal for clean rooms
Humidity Sponges™ meet the requirements of the FDA for use in direct
contact with food and drugs. The desiccant (sodium calcium
aluminosilicate hydrate) is nontoxic and is a “Generally Recognized as
Safe” (GRAS) material. Ideal for storing food/pharmaceutical samples,
electronics, PC boards, optics, chemicals, and equipment. Outer
material is made from 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). Bags are guaranteed to retain
16% moisture by weight, although typical results are 37% moisture
absorption. Each bag measures 3 x 3 x 1/4 inches and weight is 3/8
ounce.
