SPI-Dry Rechargeable and Indicating Desiccating Canister 2x4 in. (5.1 x 10.2 cm), Pk (1)

This 2" x 4" (5.1 x 10.2 cm) canister, perforated and filled with indicator silica gel, helps maintain low humidity in three cubic feet of sealed space, perfect for desiccating cabinets. When the monitor window changes from blue to pink, the gel is saturated and can be restored to its absorbent state by heating. This allows for indefinite use, and the canister can be rejuvenated by heating in a lab oven at 148 C/300 F for several hours, recycling it essentially unlimited times. Avoid heating above 148 C/300 F to prevent changes in the polyethylene plastic. For smaller space needs, consider SPI Supplies desiccant capsules.
