4378 Gas Washing Bottle, Allihn, with double action, improved by Friedrichs. 



Consists of a bottle with gas tubes fused into stopper. The tube going to the bottom is perforated and 

 enclosed in an outer tube perforated near the middle. There is also a valve in the inner tube. When the bottle 

 is filled with liquid and the connections made, the pressure of the gas forces the valve to the bottom, allowing 

 the gas to pass into the second tube, and thence into the bottle, so causing it to be twice washed. On the flow 

 of gas ceasing, the valve rises and closes the tube.
