During filling of a capillary with an electrophoresis medium, this electrophoresis medium receptacle maintains a resting state, and the capillary and the electrophoresis medium receptacle are readily sealed. The electrophoresis medium receptacle is simple in shape, the electrophoresis medium receptacle is readily manufactured, and the electrophoresis medium is readily sealed. The amount of the electrophoresis medium sealed in the electrophoresis medium receptacle is brought into approximation without limit to the amount of the electrophoresis medium filling the capillary, minimizing dead space. In this electrophoresis medium receptacle (105), a receptacle (214) filled with an electrophoresis medium (222) is maintained in a sealed state, and a septum (215) which can be pierced by a capillary cathode end (207) is provided. The pressure produced when the capillary cathode end (207) pierces the septum (215) in which the receptacle (214) filled with the electrophoresis medium (222) is sealed transports the electrophoresis medium (222) into the interior of a capillary (101). |
