The capillary electrophoresis device using one pressure-resistant syringe () is capable of automatically suctioning in polymer solution and injecting polymer solution into a capillary array (). An electric hook () is installed for pulling up the syringe plunger on a push-in action type syringe (). A check valve () is inserted between a polymer bottle () 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.
