Kleer-Vue Sorbent Boxes

• Compact size—only 2.125" x 2.125" x .8"—fits in nearly any enclosure without wasting precious storage space
• Indicating silica gel, packaged in a transparent plastic container, adsorbs moisture to retard oxidation and other defects caused by exposure to water vapor
• Perfect for packaging, transporting, and other short-term humidity protection
• Saturated boxes can be microwave-dried and reused up to 1,000 times!

The Kleer-Vue Sorbent Box is a small, perforated canister packed with indicating silica gel that will protect sensitive materials from deterioration, rust, corrosion, mold, mildew and other damage caused by moisture exposure.

Safe, Simple to Use and Regenerate
Just place a Sorbent Box in any sealed, moisture-resistant container to create a dry storage or shipping package. A single unit dries a minimum of three cubic feet of air.

The silica gel inside attracts, condenses and holds water vapor physically through surface adsorption and capillary action. As it adsorbs moisture, the blue silica gel turns pink, indicating loss of adsorption potential. To regenerate the package, simply heat it in a microwave oven. After several heating cycles of less than 45 seconds each, the silica gel releases adsorbed water vapor and turns blue again, indicating that it's ready for use. (Note: be sure to let the unit cool between cycles.) With proper regeneration, sorbent boxes can be reused 1,000 times!

Kleer-Vue Sorbent Boxes are made of chemically inert plastic and will not react with materials they come in contact with.
