An automated immunoassay apparatus which provides: time controlled incubation of a multiplicity of sample solutions, each of which comprise a mixture of (a) a sample, possibly containing an antigen or antibody intended to be assayed; (b) a solution of a known concentration of a tagged antigen or tagged antibody; and when assaying for antigen, optionally; (c) a solution of a known titer of an antibody reactable with said antigen; ISOLATION OF INCUBATED SAMPLES FROM ADDITIONAL SAMPLE SOLUTIONS INTRODUCED INTO SAID APPARATUS FOR ASSAY, WHEREBY THE SYSTEM IS ISOLATED AT A FIRST PREDETERMINED SIGNAL FROM A TIMING DEVICE, AND WHEREBY THE SYSTEM IS RECONNECTED AT A SECOND PREDETERMINED SIGNAL FROM THE TIMING DEVICE, WHEREIN THE SECOND PREDETERMINED TIME PERIOD IS SET SO AS TO ENABLE SUFFICIENT TIME TO COMPLETE A MEASUREMENT OF THE AMOUNT OF TAGGED MATERIAL BEFORE THE NEXT INCUBATED SAMPLE ARRIVES IN THE DETECTOR FOR THE NEXT SEQUENTIAL MEASUREMENT.
