Abstract: An endoscope includes an insertion section extending along a longitudinal axis and including a distal end portion, the distal end portion includes a distal end structural member including a conduit integrally formed as a through hole with the distal end structural member, the conduit configured so that a fluid flows through the conduit, the conduit includes a nozzle and a supply conduit located proximally relative to the nozzle, wherein a cross-sectional area of the supply conduit is greater than a cross-sectional area of the nozzle.

Abstract: Provided is an electrophoresis device for enhancing its analysis performance. In order to achieve the task, the electrophoresis device includes a capillary array constituted by a capillary, a capillary head for bundling an end of the capillary, an electrode holder for holding an electrode provided at the other end of the capillary and a detector provided for the capillary, a first heater for heating the capillary, and an irradiation detection unit for irradiating a light to the detector to detect a fluorescence generated from a fluorescence labelled sample in the capillary. The electrophoresis device further includes a second heater for heating the detector.

Abstract: The present invention comprises: hinge members which rotatably link a device body and a door; wires which electrically connect the door side with the device body side; and a moving-side wiring retention member and fixed-side wiring retention member which retain the wires and are attached to the hinge members. The moving-side wiring retention member and the fixed-side wiring retention member are disposed spaced apart in an axial direction of the hinge members. The moving-side wiring retention member and the fixed-side wiring retention member rotate relative to each other on the same axis in accordance with a rotation operation of the door.

Abstract: An electrophoretic apparatus that allows bubbles to be readily removed out of an electrophoretic passage. The passage for electrophoretic medium, at a connecting section where capillaries filled with electrophoretic medium are connected with a pumping mechanism for filling the electrophoretic medium, is arranged such that the side of the pumping mechanism is disposed below the side of the capillaries, so that the electrophoretic medium flows from down to up at the connecting section when filling the electrophoretic medium into the capillaries. Preferably, the passage between the capillary array and the buffer solution is controlled by using a rotary-type valve having high withstand pressure to simplify the passage structure. The dead volume of the passage can be reduced and the valuable electrophoretic medium can be efficiently used. The amount of used electrophoretic medium required for the removal of the bubble can be also reduced.

Abstract: The present invention provides a capillary electrophoresis apparatus in which a capillary is easily attached to and detached from a migration medium filling unit without mixing impurities into the capillary. Mixture of impurities such as dust is also prevented when a capillary negative-electrode end is brought into contact with a sample stored in a vessel. Furthermore, temperature control is efficiently performed in the capillary. In the capillary electrophoresis apparatus, the whole of capillary array can be supported by grasping a grip portion by hand. A migration medium filling mechanism includes a slide mechanism which moves a polymer block with respect to a capillary head. The capillary electrophoresis apparatus includes a vessel in which a sample and a buffer can simultaneously be stored. Temperatures of the capillary and an irradiation and detection unit are controlled by a temperature control function provided in a thermostatic device.
