Abderhalden's drying pistol, or just drying pistol, is a piece of laboratory glassware used to free samples from traces of water, or other volatile impurities. These days, vacuum drying has largely replaced the use of this apparatus.

[hide]General
Abderhalden's drying pistol consists of two main pieces:
- A jacketed tube flask, with a main female ground glass joint and two smaller ones on opposite sides, one male and another female. The wet material is added here.
- A bent pear-shaped Schlenk flask with a gas stopcock tube which goes in the same direction as the ground glass joint. This is where the desiccator is placed.
When assembled, the apparatus is similar in appearance to a handgun, hence its name.
