A pneumatic trough is a piece of laboratory apparatus used for collecting gases, such as hydrogen, oxygen and nitrogen. It is mainly made of glass or various fibres and are of various sizes. It was invented by Stephen Hales. See more Four items are required for gas collection with a pneumatic trough: • The trough itself, which is a large glass dish or a similar container. • A gas bottle (or bulb), to hold the gas collected. See more • Eudiometer • Pneumatic chemistry • Joseph Priestley See more The bottle is filled with water, inverted, and placed into the pneumatic trough already containing water. The outlet tube from the gas-generating apparatus is inserted into the opening of the bottle so that gas can bubble up through it, displacing the water within.
