A sample analyzer (10), including an incubation mechanism (400), which is used for performing incubation on liquid in a reaction vessel ; and a uniform mixing mechanism (300), which is independently arranged relative to the incubation mechanism(400) and has a transport
station (321) and a uniform mixing
station (322), wherein the uniform mixing mechanism (300) includes a carrying member (310), and the carrying member (310) drives the reaction vessel to circularly move between the transport
station (321) and the uniform mixing station (322); and the carrying (310) member conveys the reaction vessel, which is input from the transport station (321), to the uniform mixing station (322) and conveys the reaction vessel to the transport station (321).Input and uniform mixing procedures of different reaction vessels on the carrying member (310) can be carried out at the same time, and the test flux of the sample analyzer is improved.
