Liquid sample analysis device

摘要

A liquid sample analysis device includes a holder part 11 holding a test piece 1, an optical system 20 that optically detects a reaction state of a liquid sample and a reagent, and a support member 30 that integrally supports the holder part 11 and the optical system 20. The orientation of the test piece 1 is changed with respect to the direction of gravitational force by rotating the support member 30.
