Abstract: Provided is an automated analyzer comprising a temperature regulator that can be made more compact in size while maintaining high-precision temperature regulation. In a temperature-regulating unit (20) of the automated analyzer, a first chemical reservoir (1) is constituted by a large-diameter spiral-shaped pipe, and a second chemical reservoir (2) is constituted by a large-diameter chemical reservoir container. The first chemical reservoir (1), which is positioned upstream of the second chemical reservoir (2), has an internal capacity that is set so as to be greater than the volume of a single discharge of each of syringe pumps (29, 30, 31), and the second chemical reservoir (2) also has an internal capacity (volume) that is set so as to be greater than the volume of a single discharge of each of the respective syringe pumps (29, 30, 31).

Abstract: It is an object of the present invention to provide an electrophoresis device that allows for reducing the temperature variation in the thermostat and that makes it easy to attach/detach the capillary. The electrophoresis device according to an aspect of the present invention includes: a capillary array unit that includes a capillary and a support that supports the capillary; a pump mechanism having one end of the capillary being connected thereto and for delivering a separation medium to the capillary; a detection unit that emits light to a portion of the capillary and performs a measurement on a sample in the capillary; and a thermostat that houses the capillary therein and performs temperature control on the capillary, in which the thermostat includes a heat source and a fan that sends air into the thermostat, and in which the thermostat or the capillary array unit includes a straightening plate.
