Pneumatic troughs require a liquid such as water. Scientists also have used mercury in pneumatic troughs, but usually only for the collection of water soluble gases. Health and safety issues surrounding mercury generally prohibit its use in modern day pneumatic troughs. 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 A way to support the gas bottle or bulb, such as a Beehive shelf or a hanger see picture A liquid in the trough 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.

Disadvantage of the pile Volta s battery consisted of brine soaked pieces of cloth sandwiched between zinc and copper discs, piled in a stack. This resulted in electrolyte leakage as the weight of the discs squeezed the electrolyte out of the cloth. Advantage of the trough Cruickshank solved this problem by laying the battery on its side in a rectangular box. The inside of this box was lined with shellac for insulation, and pairs of welded together zinc and copper plates were laid out in this box, evenly spaced. The spaces between the plates the troughs were filled with dilute sulfuric acid . So long as the box was not knocked about, there was no risk of electrolyte spillage.
