STOPPER FOR REMOVING VOLATILE SUBSTANCE, VESSEL FOR REMOVING VOLATILE SUBSTANCE, AND APPARATUS FOR REMOVING VOLATILE SUBSTANCE

摘要

[PROBLEMS] To provide a stopper for removing a volatile substance, which can vaporize and remove volatile substances such as solvents in a simple and highly efficient manner, and a vessel for removing a volatile substance using the stopper for removing a volatile substance, and an apparatus for removing a volatile substance using the vessel for removing a volatile substance. [MEANS FOR SOLVING PROBLEMS] A vessel (1) for removing a volatile substance comprises a vessel (2) for storing a solution containing the volatile substance, a volatile substance removing stopper (3) for closing the opening of the vessel (2). A through-hole (3a) for discharging a vaporized volatile substance is provided in the stopper (3). Further, a gas introduction port (3b) is provided on the upper edge of the stopper (3). Further, a gas discharge port (3c) is provided on the lower edge of the stopper (3). A groove (3d) connecting the gas introduction port (3b) to the gas discharge port (3c)is provided on the side face of the stopper (3). Upon evacuation of the inside of the vessel or tube (2), an external gas is passed through the groove (3d) and is blown at a high speed into the tube (2) through the gas discharge port (3c), and, while colliding against the internal wall of the tube (2), is spirally rotated by centrifugal force along the inner wall of the tube, whereby the volatile substance is kicked up and stirred by a gas stream to increase the surface area and thus to promote the vaporization of the volatile substance.
