In chemistry, the wing apparatus is a device often used in synthetic chemistry for carrying out reactions under an inert atmosphere of nitrogen or argon to prevent reactions with oxygen or moisture in the air. It typically consists of a double-neck flask with one neck for adding reagents and the other for attaching to a gas source for purging the vessel with inert gas. This setup helps maintain a controlled environment for sensitive reactions.
