ABSTRACT:
A turntable is arranged rotatably in both directions and a plurality of reaction vessels are arranged along a periphery of the turntable. Along the circumference of turntable are arranged a reagent delivery unit for delivering a given amount of reagent into successive reaction vessels, a sample delivery unit for delivering a given amount of samples into successive reaction vessels and a plurality of photometering units for measuring an absorbance of a test liquid contained in each reaction vessel. The turntable is first rotated in a backward direction by four steps and then is rotated in a forward direction by five steps, so that the turntable is advanced in the forward direction by one step at the end of the forward movement. Between successive backward and forward movements the test liquid is measured at a first time by the photometry unit and between successive forward and backward movements the same test liquid is measured at a second time by the same photometry unit and in this manner successive test liquids are measured twice by each of the photometry units. An analytical result can be obtained by processing all the measured values supplied from all the photometry units.
