Abstract: Provided is a capillary array unit configured to facilitate attaching/detaching operation. A capillary array unit includes a capillary, a load header provided at one end of the capillary, a capillary head provided at the other end of the capillary, a detection section provided at a portion of the capillary, and a holder holding the capillary. The holder includes a first holding section holding the capillary in a curved shape, a second holding section linearly holding the capillary, and a guide to move the second holding section in a predetermined direction.

Abstract: An electrophoresis device of the present disclosure includes: a capillary filled with a phoresis medium; a buffer container accommodating a buffer solution; a storage portion storing a sample container accommodating a sample; at least one autosampler transporting each of the sample container and the buffer container; and a control unit controlling driving of the autosampler, in which the control unit drives the autosampler such that, while the buffer container is disposed at a capillary position where one end portion of the capillary is positioned, the sample container is transported from the storage portion to a standby position near the capillary position, and, when the buffer container has been transported from the capillary position to the standby position, the sample container is transported from the standby position to the capillary position.

Abstract: Aiming at achievement of timely installation of the cartridge, sequential execution of the pretreatment process in the order of installation of the cartridge, and individual shifting of the process to the electrophoresis process upon completion of the pretreatment process, the electrophoresis device according to the present invention includes a plurality of capillaries each filled with a separation medium, a thermostat chamber for holding the capillaries at a predetermined temperature, an irradiation detector which executes light irradiation and detection in an electrophoresis process using the capillaries, a high voltage power supply unit for voltage application to the capillaries, a liquid feeding mechanism for feeding the separation medium to the capillaries, and an autosampler for conveying containers each holding a reagent or a sample to the capillary. The voltage application to the capillaries by the high voltage power supply unit is controlled for each of the capillaries.
