An immunity analysis apparatus for use with magnetic particles in which a sample is transferred to a reaction vessel and the reaction vessel is conveyed past several devices for adding and agitating a magnetic particle solution, adding a stroma solution, absorbing the particles to an inner wall of the reaction vessels to remove the reaction solution, adding an enzyme labelling antibody solution, absorbing the particle on an inner wall a second time to remove the resulting solution, adding a stop solution, measuring the result, and cleaning the reaction vessels for a reuse. The device additionally has structure for agitating the magnetic particle reagent solution containers and moving a pipet arm independent of an L-shaped agitating rod arm during a portion of its movement to supply the reaction vessels with the magnetic particle solution.
