<P>PROBLEM TO BE SOLVED: To provide a vessel and a rod which are used for collecting magnetic particles from a liquid or for releasing the magnetic particles into another liquid. <P>SOLUTION: This invention is related to the vessel and the rod used together with the vessel for the purpose of collecting the magnetic particles from the liquid containing the particles in the vessel or for the purpose of releasing the particles into another liquid in the vessel. When the rod (3) is inserted into the vessel (1), the interstice between the vessel and the rod at every point is large enough to prevent the formation of a liquid ring or a ring part rising along with the rod. In such a state the liquid can be prevented from being removed along with the rod from the vessel. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
