Abstract
An electrophoretic apparatus that allows bubbles to be readily removed out of an electrophoretic passage. The passage for electrophoretic medium, at a connecting section where capillaries filled with electrophoretic medium are connected with a pumping mechanism for filling the electrophoretic medium, is arranged such that the side of the pumping mechanism is disposed below the side of the capillaries, so that the electrophoretic medium flows from down to up at the connecting section when filling the electrophoretic medium into the capillaries. Preferably, the passage between the capillary array and the buffer solution is controlled by using a rotary-type valve having high withstand pressure to simplify the passage structure. The dead volume of the passage can be reduced and the valuable electrophoretic medium can be efficiently used. The amount of used electrophoretic medium required for the removal of the bubble can be also reduced.
