750 Gram Rechargeable Silica Gel Canister

This Silica Gel Canister is our Most Popular Unit for Gun Safes and Similar Storage Areas

The heavy-duty perforated steel canister contains 750 grams of silica gel to protect your valuables from condensation and to stop rust, mildew, corrosion, and spoilage. The 4" diameter x 5" tall unit protects 57 cubic feet of enclosed space. A built-in indicator turns from orange to dark green to signal it has reached its maximum moisture saturation level. Once that level has been reached, the unit can easily be recharged in any conventional oven (2-3 hours at 250 degrees F). The units can be recharged as often as needed for lifetime protection. Silica gel is inert and non-toxic. Will not emit harmful vapors, stain, or cause chemical reaction. Safe to use with sensitive materials.

The units are extremely effective at protecting your valuables such as family photos, documents, silverware, musical instruments, seasonal storage, grain, medicines, clothing, guns, electronics, jewelry, food, leather, coin and stamp collections, tools, collectibles, and other valuables.

750 Gram Rechargeable Silica Gel Canister is ideal for trunks, cabinets, vaults, safes and more. Heavy-duty container is preferred by police armories, hospitals, museums, and collectors.

Now Cobalt Chloride free! The 750 gram canisters now contain indicating gel that changes from orange to dark green when the silica gel needs to be recharged. The older style (blue to pink) contains Cobalt Chloride, a possible carcinogen to humans. The reformulated silica gel has the same moisture absorption capacity and effectiveness, but does not contain Cobalt Chloride.
