Abstract
A body fluid sample and a reagent are reacted in a reaction container, and after measuring the reaction solution the reaction solution is discharged from the reaction container. The vacant reaction container is washed by charging a detergent solution containing plural kinds of surface active agents through a nozzle of a washing mechanism. The detergent solution is a mixed solution containing polyoxyethylene alkyl ether, polyoxyethylene polyoxypropylene glycol ether, N-acyl amino acid salt and polyacrylic salt. By the washing method in accordance with the present invention, it is possible to eliminate bad effects due to incomplete washing of reaction containers in an apparatus for automatically successively analyzing biological samples.
