Automated immunoassay analyser.

摘要

An automated immunoassay analyser 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 upperstream to downstream in the order referred to in which the device A is for injecting the sample comprising a vertically and horizontally 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.
