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.
