First Claim
Patent Images
1. An automated chemical analyzer comprising:
- a plurality of turntables concentrically arranged, each of said turntables having a circumferential reaction line including a plurality of reaction receptacles disposed coangularly with an interval therebetween;
driving means for rotating each of said turntables independently;
light source means for emitting a light beam passing through a reaction receptacle disposed on a reaction line of one of said turntables and passing through the interval or intervals disposed on the reaction line or lines of said remaining turntables; and
light-measuring measuring means for measuring said light beam, said reaction lines of said turntables disposed between said light source means and said light-measuring means.

Abstract
Two turntables are arranged in a concentric array with a plurality of reaction tubes arranged on each respective turntable, in which one turntable is rotated while, on the other hand, the other turntable is stopped. It is possible to measure the intensity of a light beam passed through the reaction liquid within the reaction tube on the turntable being rotated. The pouring of a sample, pouring of a reagent and washing/drying are achieved with respect to the reaction tubes on the turntable being stopped. The pouring of the sample and reagent and washing of the tubes are achieved parallel with the extraction of the measured data, thus assuring a shorter analytical handling time.
