Patent ID: 7459068

Claim:
A multi-capillary electrophoresis apparatus comprising: a multi-capillary array having a plurality of capillaries filled with an isolation medium for isolating a sample, a sample injecting end on one end thereof and a detector part for acquiring information depending on the sample at a position remote from the sample injecting end, the detector part being enclosed in a container; a voltage applying part for applying a voltage to an electrification path between the sample injecting end and the detector part; a thermostat oven containing the multi-capillary array except for portions that protrude from the thermostat oven, wherein the thermostat oven has a first temperature controlling part for controlling a temperature of the thermostat oven; a flow path, filled with the isolation medium and connected to the multi-capillary array; a second temperature controlling part for controlling a temperature of a portion of the multi-capillary array located between the detector part and the thermostat oven; and a third temperature controlling part capable of controlling a temperature of the multi-capillary array located beyond the detector part; wherein the first temperature controlling part is capable of controlling a temperature of the thermostat oven, separately from the temperature of the multi-capillary array located beyond the detector part and controlled by the third temperature controlling part.
