A swan neck flask, also known as a gooseneck flask, is a round-bottom flask with a narrow s-shaped tube as its opening to reduce contact between the inner contents and external environment.

A gooseneck is a semi-rigid, flexible joining element made from a coiled metal hose. Similar to its natural counterpart , it can be bent in almost any direction and remain in that position. [ 1 ] Areas of application for goosenecks are movable brackets for lights , magnifying glasses , microphones and other devices. [ 2 ]
Gooseneck vent with check valve being repainted. A gooseneck (or goose neck) is a 180° pipe fitting at the top of a vertical pipe that prevents entry of water.
