ABSTRACT:
After a sample stage moves and brings a sample titer plate toward and into contact with a capillary array end, a high voltage is applied across electrodes for a prescribed time for injecting samples. Thereafter an electrophoresis reservoir comes into contact with the capillary array end, for starting electrophoresis. When electrophoresed/separated DNA fragments pass through a detection part, an excitation/photoreceiving optical system is scanned so that photomultipliers detect fluorescence from four types of fluorescent materials labeling the samples. The excitation/photoreceiving optical system comprises an epi-optical system and a confocal optical system, and is scanned at a high speed.
