Abstract: At a wall constituting a space for a thermostatic oven in an electrophoresis apparatus, a capillary array attachment portion is formed which permits attachment of a plurality of capillary arrays having different length. Thereby, a selected capillary array constituted by collecting a plurality of capillaries can be easily attached to the electrophoresis apparatus depending on measurement purpose.

Abstract: In a case where the temperature of capillaries cannot be controlled rapidly in accordance with the change of the amount of heat generated from the capillaries, the phoretic speed of the sample is not controlled constant to lower the analyzing performance for the sample. This invention intends to stabilize the electrophoretic speed. The surface of a substrate on which a plurality of capillaries are arranged is in contact with a member capable of temperature control thereby controlling the temperature of the capillaries. Since a member capable of controlling the temperature and the capillaries are in direct contact with each other according to the invention, the temperature of the capillary can be controlled rapidly at a high accuracy, so that electrophoretic speed is stabilized.

Abstract: The capillary electrophoresis device using one pressure-resistant syringe (125) is capable of automatically suctioning in polymer solution and injecting polymer solution into a capillary array (100). An electric hook (131) is installed for pulling up the syringe plunger on a push-in action type syringe (125). A check valve (124) is inserted between a polymer bottle (123) and syringe to prevent solution from flowing back into the polymer bottle. As a result, one syringe portion of polymer solution can be suctioned and injected, a large volume of polymer solution can be continuously used and device processing capability is improved.

Abstract: The present invention easies a connection between electrodes of a capillary array device and a connection plate for supplying a high voltage to the electrodes. According to the present invention, a connection plate 23 and hollow electrodes 20 are connected without solder but via a spring force. Alternatively, the hollow electrodes 20 can be connected to the connection plate 23 by utilizing volume elasticity of the connection plate.

Abstract: An injection syringe 14 for injecting a gel into a capillary 111, a charging syringe 15 for charging the injection syringe 14 with the gel 10 are attached to a block 17. A check valve 16 is inserted between the both syringes, and the check valve 16 works so as to prevent the gel 10 from flowing back to the charging syringe 15. As the result, the gel charging can be automated, and accordingly the processing ability of the electrophoretic instrument can be improved.
