Abderhalden's drying pistol

Abderhalden's drying pistol. Note the inner barrel (to be connected to the vacuum source), and the outer barrel connected to the pot. The condenser is not attached.

Abderhalden's drying pistol is a piece of laboratory glassware used to free samples from traces of water, or other impurities. It is called a "pistol" because of its resemblance to the firearm. Its use has declined due to modern hotplate technology and vacuum pumps. The apparatus was first described in a book edited by Emil Abderhalden.[1] The drying pistol allows the sample to be dried at elevated temperature; this is especially preferred when storage in a desiccator at room temperature does not give satisfactory results.[2]
