Abstract
A microchip electrophoresis apparatus includes a microchip, a dispensing part, a suction part, and a control part. The control part is configured to perform a buffer solution filling step and a liquid surface aligning step. In the buffer solution filling step, a buffer solution is filled in a channel of the microchip, and also a liquid surface level of the buffer solution in a first reservoir and a liquid surface level of the buffer solution in a second reservoir provided on the other end of the channel are set to a predetermined level or more. The liquid surface aligning step is performed after the buffer solution filling step. In the liquid surface aligning step, tips of a first suction nozzle and a second suction nozzle are lowered from above the first reservoir and the second reservoir to the predetermined level while allowing the first suction nozzle and the second suction nozzle to perform suction operation, such that the buffer solution in the first reservoir and the second reservoir is sucked in order from a surface layer side, and aligning the liquid surface level of the first reservoir with the liquid surface level of the second reservoir.
