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.
Contents
[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.
Operation
To be added
Doug's Lab has made a tutorial, as has Tom's lab.
Availability
Abderhalden's drying pistol can be purchased from lab suppliers, or online from eBay and Amazon.
