Abstract
An automatic analysis apparatus is disclosed which provides for various analytical operations in clinical diagnosis and experiments including measuring the changes in light absorbance of a large number of samples mixed with different reagents in a progressive manner, biochemical, electrolytical, fluorescence, and immunological analysis and EIA analysis of samples in bead solid phase. A plurality of samples are maintained, together with diluents and emergency samples, in an ordered sequence on a sample table rotatably disposed which is rotated by drive means in a stepping manner to move the samples progressively to a predetermined suction position at which a sample pipetter picks up a measured amount of sample and dispenses it to one of a plurality of reaction containers that are arranged in an ordered sequence on a reaction table rotatably disposed, preferably about said sample table. A first and a second reagent table are provided, each carrying a plurality of reagents different in kind from one another, selected for various analyses to be performed. A first and a second reagent pipetter are provided and operated to pick up a measured amount of a particular reagent and mix it with…
