Reaction incubation device, immunity analyzer and reaction incubation method

The invention discloses a reaction incubation device, an immunity analyzer and a reaction incubation method. The reaction incubation device comprises a reaction unit (10) and a transfer unit (20), wherein the reaction unit (10) is use for bearing and incubating a reaction container; the transfer unit (20) is used for removing the reaction container in and out of the reaction unit (10); the reaction unit (10) comprises a rotating device (11); the rotating device (11) is provided with an incubation position; the incubation position moves a predetermined angle theta at an interval of fixed time T along with the rotating device (11); and the transfer unit (20) removes the reaction container out of the incubation position according to variable incubation time t1. Flexible and variable incubation time can be simply and efficiently achieved, and the problems that control is complicated, the reliability is low and high-speed automation is not easy to achieve in the prior art to achieve the variable incubation time are effectively solved.
