Reusable Desiccant Canisters

Reusable Desiccating Canisters protect all types of articles from deterioration, rust, corrosion, mold, mildew and other damage caused by moisture or high humidity. Simply place the canister together with the article to be protected in a tightly closed or sealed moisture resistant container. the canister will rapidly and actively desiccate the surrounding air and keep it that way to protect against moisture damage. Avaialable at:

Reusable Desiccating Canisters have several distinct advantages:

• Reusable over and over
• Regenerated easily by microwave or conventional oven
• High moisture capacity
• Easy to use

Typical applications include:

• Laboratory equipment and chemicals
• Cameras, lenses, photos and film
• Scientific instruments
• Medical and dental instruments
• Tools
• Museum and historical artifacts
• Clothing and fabrics
• Shoes and leather articles

The "forever" desiccant for a variety of applications.
The reusable canister is a small, perforated canister containing an indicating silica gel. The case is lightweight yet strong, designed to withstand years of use. The desiccant content has a reversible action. Once it has adsorbed all the moisture it can hold, indicated by a color change from blue to pink it can be regenerated easily by microwave or conventional oven. After regeneration, the canister will be capable of readsorbing its full capacity.

High moisture capacity.
The desiccant material within the canister attracts water vapor and holds it physically through surface adsorption and capillary condensation. It has a tremendous number of microscopic pores which give it a high moisture capacity. One canister will maintain a safe level of humidity in three cubic feet of sealed space.

Easy to monitor and regenerate.
Available in a plastic translucent plastic case. When the desiccant turns pink, it indicates that a saturation point has been reached. Regeneration can be achieved by microwave or conventional oven.

• Conventional Oven - (Metal or plastic case) - Heat the canister in vented oven at 300°F for three hours.
• Microwave Oven - (Plastic case only) - Heat the canister in microwave on high (using a 900 watt microwave) in 3 minute intervals until beads turn blue. Time may vary depending on wattage of the microwave used to regenerate.

CAUTION: Allow sufficient cooling before removing the canister from an oven or microwave to reduce risk of personal injury. Damage to desiccant may occur in microwave ovens over 900 watts or from temperatures above 325°F. Under extreme humid conditions, desiccant may achieve rapid saturation which reduces absorption capacity.
