A gas washing bottle is a lab device whose primary use is to inject a stream of gas through a liquid, in a closed flask.

Description

A gas washing bottle consists of a (usually) cylindrical bottle/flask with a female ground glass joint, where a specialized male ground glass joint stopper with two glass tubes can be attached. The stopper has two external glass tubes, one enters the stopper from one side, taking a 90° angle and extends until near the bottom of the flask, while the other is connected directly to the stopper.

Dreschel washing bottles are a very common model.

How to use a gas washing bottle

To properly use a gas washing bottle, you must do the following:

  • Place the gas washing bottle in a secure place
  • Fill the bottle with the choice liquid
  • Grease the joints
  • Connect the tubing to the 2 external glass tubes from the bottle, with the gas entry tube to the long tube, and the gas exit to the shorter tube.
  • Begin pumping gas through the bottle

DIY gas washing bottle

A simple gas washing bottle can be made by inserting two tubes through a silicone rubber stopper or some other type of stopper, with the entry tube longer than the exit tube and place the said stopper in a flask or tube opening.

Uses

Gas washing bottles are commonly used to remove gaseous side-product from reactions or to dissolve various gasses in liquids, to make a solution.

Gas washing bottles can also be filled with a drying agent like calcium chloride and used as a drying tube.
