A selective or sequential access analyzer for clinico-chemical analyses and for immunological tests, which includes a central microprocessor, a diluting device (7) connected to a revolving sampling system (13) or assembly and provided with a sampling probe (12)= a fixed reagent-supporting tray (14) concentrically external with respect to said sampling assembly= a first revolving sample bearing plate (17) in such a position as to be within the reach or of said sampling probe= a second revolving plate, independent of the first one, and concentrically external to the same provided with segments (19) bearing reaction test-tubes (20) and placed in such a way as to be within the reach of said sampling probe= an aspiration system (21) bearing a probe (23) is provided diametrically opposite to said sampling assembly with respect to said two concentric plates= and a reading photometer (25) connected to said aspiration probe through a tube= said analyzer also includes six microprocessors operatively interconnected to each other and to the central microprocessor, respectively, for the diluting device, for the sampling assembly, the first revolving plate, the second revolving plate, the aspiration probe and the reading photometer while the motion of said diluting device, of the sampling assembly, of the first and the second revolving plates, of the aspiration probe and the reading photometer is obtained through stepper motors controlled by the individual microprocessors for each of these elements.
