Bottle, Gas Washing

A gas washing bottle consists of a cylindrical bottle/flask with a female ground glass joint, where a specialized male ground glass joint stopper with two glass tubes is attached. The stopper has two external glass tubes, one enters the stopper from one side, taking a 90° angle and extends until near the underside of the flask, while the opposite is connected on to the stopper. Some special kinds of gas washing bottles have a fritted glass.
