ABSTRACT:
A chemical analyzer has turn tables respectively carrying reaction vessels, sample containers and reagent containers disposed thereon in circular rows. A sample pipetting mechanism and a reagent pipetting mechanism are provided to transfer predetermined amounts of sample and reagent solution from a sample container and from a reagent container into a reaction vessel. The thus transferred sample and reagent solution are mixed in the reaction vessel by a stirrer comprising a piezoelectric element which is disposed in non-contacting relationship to the sample and reagent solution in the reaction vessel and is electrically energized to generate a sound wave which causes a circulating flow of the reagent solution in the reaction vessel whereby the sample and the reagent solution are mixed in a non-invasive manner.
