Sealable canisters, or cabinets, known as desiccators keep contents dry (and dust-free) with the help of desiccant. These economical storage containers are used for electronics, reagents, and other humidity-sensitive items. While there are at least four types of desiccators, the most typical are non-vacuum desiccators and vacuum desiccators. Usually, vacuum desiccators include a stopcock to enable internal air to evacuate, thus creating lower humidity levels. A separate vacuum pump may be necessary but some models include a built-in pump. From polypropylene to polycarbonate to glass and stainless steel, desiccators are crafted in various materials and available in a variety of sizes. For a more significant investment, you can choose a static-free desiccator for instruments that are sensitive to electrostatic discharges. Electronic desiccators automatically remove moisture from desiccant and regenerate it every five hours. Some also offer built-in thermohygrometers. Space-saving units t...
