したことを特徴とする真空封入管。 It consists of a connection part that connects to a vacuum device, a sealing part that is scheduled to be separated later, and an enclosure tube body that houses the material or sample, and an upper member and a lower member are connected between the sealing part and the enclosure tube body. In the vacuum-sealed tube separated into two, the shape of the lower end opening of the upper member is the conical surface of a cone that gradually increases in diameter from the lower end of the sealed part, and the maximum inner diameter of the cone is the shape of the upper end opening of the lower member. A vacuum-sealed tube characterized by having a diameter slightly larger than the outside diameter of the tube.
