Mariotte bottle

Pronunciation: mah-rē-ot′

Definition: a stoppered bottle with bottom outlet, used as a reservoir for constant infusions; air enters only by bubbling through a tube extending down through the stopper almost to the bottom; a partial vacuum thus supports the variable height of liquid above the air inlet, providing a constant gravity head for outflow.
