Two Ways the 500 ml Bottle Is Used
As a gas generator, it holds enough solid and acid to give carbon dioxide or hydrogen for a longer run before recharging. Acid goes in through a thistle funnel whose stem dips below the liquid, which seals the funnel so gas cannot escape up it, and the gas leaves through a delivery tube in the second neck.
As a safety bottle between a filter flask and a water pump, it stands empty with short tubes in both necks. If the water pressure drops and water is sucked back, it collects in the bottle instead of running into the filtrate.
