The Bel-Art Scienceware 420460000 desiccant canister to absorb water in desiccators or other spaces up to 0.09 cubic meters (3 cubic feet). The desiccant contains 80 to 90 percent silica gel and 0.5 percent cobalt chloride. This product is designed to be re-used – it can be regenerated repeatedly without losing drying performance. The color of the desiccant, viewable through a window, starts as blue and changes to pink when saturated. The canister is 1.3 x 10.2 x 5.1cm (0.5 x 4 x 2") (H x W x D). (H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.) This product is suitable for use in closets, containers, toolboxes, and other storage areas to prevent rust and moisture damage.
Desiccators are sealable containers used to remove water from a sample, or to preserve moisture-sensitive electronics or lab consumables, typically in laboratory, electronic, and aerospace applications. Desiccators are often used with desiccants, which are drying agents such as silica gel or activated charcoal placed under a removable platform. Standard desiccators are typically lidded jars used with a desiccant. Vacuum desiccators have a stopcock that allows air evacuation from the desiccator. Gas purge desiccators use a gas port to introduce nitrogen or other gasses, creating a controlled environment. Vacuum and gas purge desiccators may also be used with desiccants. Many desiccators are used with vacuum grease, which helps create a seal.
