Provided is an electrophoresis device that, by electrophoresis, feeds a sample into capillaries and optically detects the sample, the electrophoresis device being provided with capillaries, a capillary head provided at the distal end of the capillaries, a phoretic medium-filled container used for electrophoresis and filled with a phoretic medium, a guide member that covers the side surface of the phoretic medium-filled container, a seal member that seals from below the phoretic medium filled in the phoretic medium-filled container, and a plunger that presses the seal member.

Electrophoresis method

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.

A capillary cartridge achieves both improvement of attachability and improvement of heat dissipation performance for realizing short-time analysis. A heat dissipation body is provided between a capillary having a detection unit provided in a part thereof and a plate-like support body that supports the capillary, and temperature increase inside the capillary is suppressed by the heat dissipation body, and thereby, electrophoresis can be performed under a high voltage application condition where the amount of heat increases and analysis time is reduced. In addition, it is possible to redress complexity of an operation by reducing a fixing place at the time of attachment to only a detection unit and an electrode holder by using an integration structure in which the capillary, the supporting body, and the heat radiating body are integrated.

Provided are a bubble eliminating structure and a bubble eliminating method which eliminate bubbles in a liquid by agitating the liquid, and an agitating method using the same. A first groove, which is an upstream bubble eliminating groove, and a second groove, which is a downstream bubble eliminating groove, are branched from a mixing well. After starting suction of the liquid from mixing wellinto the first groove, suction of the liquid from the mixing wellinto the second grooveis started, and after completion of discharge of the liquid from the first grooveinto the mixing well, discharge of the liquid from the second grooveinto the mixing wellis completed. This operation is repeated to eliminate bubbles.

An electrophoresis device has: a sample tray () on which there are placed a positive-electrode-side buffer solution container () containing a buffer solution and a phoresis medium container () containing a phoresis medium, and which is driven in a vertical direction and a horizontal direction; a thermostat oven unit () that holds a capillary array having a capillary head in which a plurality of capillaries are bundled in a single unit at one end thereof in a state where the capillary array being held in a state in which the capillary head protrudes downward, and that keeps the interior temperature constant; a solution-delivering mechanism () for delivering the phoresis medium in the phoresis medium container to the capillary array from the capillary head; and a power source for applying a voltage to both ends of the capillary array. Holes for insertion of the capillary head are provided in upper sections of the positive-electrode-side buffer solution container and the phoresis medium container. The thermostat oven unit is provided with a first lid member () that is positioned above the sample tray and seals the upper section of the positive-electrode-side buffer solution container while the phoresis medium is being delivered by the solution-delivering mechanism.

Grooved noodles have three grooves formed along the noodle length direction. The transverse cross section of the noodle length has a substantially circular main outer shape. The grooves are positioned in the transverse cross section of the noodle length at 120&#xb0; intervals in the circumferential direction, and extend in the same rotation direction relative to the center point of the transverse cross section of the noodle length. Each groove has a pair of mutually facing sides that extend from the opening of the groove toward the deepest part of the groove, a first opening end on the side closer to the center point out among the pair of sides, and a second opening end on the side farther from the center point among of the pair of sides. The acute angle formed in each groove by a straight line passing through the first opening end and the deepest part and a straight line passing through the first opening end and the center point is 12-28&#xb0;. The area of a center region in each of the three grooves forming a triangle has three straight lines passing through the deepest part and the midpoint between the first opening end and the second opening end has a value of 6-34% relative to the area having the main outer shape when the three grooves are not present. The noodle length occupies 85% or more of the center region.

A cartridge sealed from ambient air is used to send a liquid without causing the liquid to contact the fluid inside the cartridge. Inside of the cartridgesealed from ambient air are provided chambers that send and receive reagents, and an elastic body membraneis attached to the bottom surface. The cartridge main bodydoes not have a groove or anything else that becomes a channel, and the membraneis not bonded to portions that become channels. A channel, not formed in a normal state, is formed upon deforming the membraneunder air pressure in the unbonded portion, and the fluid is moved inside. A valve function is provided at an inlet of each chamber, and the fluid is internally moved in any direction with channel deformation.
