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.
