A sealed vessel with a plate above a drying agent.
Also known as: Drying vessel laboratory, Vacuum desiccator
A desiccator is drawn as a heavy sealed vessel with a perforated plate near its middle, a drying agent below it and a ground-glass lid above.
Keeps a sample dry, the plate holding it above a drying agent in the base.
Contexts: Laboratory
Works by keeping moisture out rather than by removing it from the sample, so what it does is preserve a dry state rather than produce one.
Contexts: Laboratory
