PROBLEM TO BE SOLVED: To provide a compact spectrophotometer capable of reconciling a pumping function for sending a sample having a small flow rate into a flow cell by drawing a flexible tube through, with a function capable of measuring a plurality of samples. SOLUTION: In this spectrophotometer, light having a specific wavelength is transmitted through a cell for storing a sample, and a quantity of light having a wavelength absorbed into the sample or transmitted therethrough is detected, while keeping the wavelength constant or changing it, to thereby measure a component of the sample or the component amount included in the sample. The spectrophotometer includes a motor, and a motor control part for controlling rotation of the motor, and has a constitution provided with a receiving part enabling another shaft to be mounted thereon or dismounted therefrom, on the end of a rotating shaft of the motor, wherein units including the cell can be mounted on the receiving part or dismounted therefrom. The units include a unit including the pumping function for sending the sample having the small flow rate into the flow cell by drawing the flexible tube through, and a unit including a turret for rotating the plurality of samples.
