Abstract:
1. A biochemical analysis method, comprising the steps of: i) loading a plurality of samples and a plurality of dry chemical analysis elements, which are necessary for analyses of the samples, on a circular sampler tray, having a rotating disk such that, the rotating disk supports the loaded plurality of samples and the dry chemical analysis elements, ii) sucking each of the samples, which have been loaded on the sampler tray, with a spotting nozzle unit, iii) spotting the sucked sample onto one of the dry chemical analysis elements with the spotting nozzle unit, and iv) supporting a plurality of nozzle tips each of which is operable to be fitted to a spotting nozzle of the spotting unit, a plurality of diluent liquid vessels and a plurality of mixing cups by the rotating disk, and v) keeping a temperature of each of the dry chemical analysis elements, which have been spotted with the samples, at a constant temperature in an incubator, wherein an element conveying member is located within the sampler tray, the element conveying member pushing each of the dry chemical analysis elements from a center side of the rotating disk and thereby conveying each of the dry chemical analysis elements, and the rotating disk is provided with a path for the element conveying member besides sections for supporting the plurality of the dry chemical analysis elements.
