ABSTRACT:
An automated immunoassay analyzser comprising a transfer route on which test plates each having a plurality of chambers for immunological reaction opened upwards are transferred continually with a constant interval of time, and devices of at least A, B, C and D described below which are arranged on the transfer route from upstream to downstream in the order referred to in which the device A is for injecting the sample comprising a vertically and horizonally driven support, a pipet fixed to the support, and a nozzle tip usable for a single sample and removably attached to the lower end of the pipet, the device B is for B/F separation and the device C is for injecting the substrate solution and both devices are integratedly combined and comprise a vertically and horizontally driven support, a washing tube supported by the support, a temperature controllable solution reservoir block fixed to the support, a substrate injection tube provided to the lower side of the reservoir block, the washing tube and the substrate solution injection tube being arranged in alignment and spaced each other according to the pitch of the cup arrangement, and the device D is for photometry with which to measure optically detectable changes caused in the substrate in the chamber of immunological reaction.
