Rechargeable and Indicating Desiccating Canister

This 2" x 4" (5.1 x 10.2 cm) perforated canister is packed with an indicator silica gel to maintain a low level of humidity in three cubic feet of sealed space - ideal for our desiccating cabinets. When the monitor window turns from blue to pink, the gel is saturated and needs only to be heated to restore it completely to its former absorbent state. In this manner the canister can be used indefinitely. These canisters can be rejuvenated by heating in a lab oven for several hours at 148° C/300° F driving off the absorbed moisture and recycled this way for an essentially unlimited number of times. We would advise against heating above 148° C/300° F because changes will start to occur in the polyethylene containment plastic. For applications where smaller space requirements must be met, consider the SPI Supplies® brand of desiccant capsules.
