Cole-Parmer DC-400 Automatic Desiccator Cabinet with N2 Purge Port, One Shelf; 50 L

A sealable canister, or cabinet, known as desiccator keep contents dry (and dust-free) with the help of desiccant. These economical storage containers are used for electronics, reagents, optical equipment, electronic parts, PCB boards, reagents and other humidity-sensitive items and are sealed to absorb moisture. Once a moisture-sensitive object is placed inside the desiccator with the desiccant (or drying agent), the object will remain dry or at a set humidity level below ambient on adjustable automatic cabinets. These canisters or cabinets are sometimes referred to as desiccant dryers or desiccant dehumidifiers. Desiccators are important tools for scientists who perform chemical reactions because the units help them ensure accurate chemical measurements before starting a chemical reaction. Desiccators also are used to transport and store samples for short- or long-term.
