Abstract

PURPOSE:To prevent the clogging of suction nozzles by solid substances in a sample by a method wherein a cleaning liquid is ejected from suction nozzles at the time when they are not sucking the sample. CONSTITUTION:Elastic tubes 11, 12 are pressed by rollers 13, 14. By this, sample 3 and diluent 4 are sucked respectively from the ends of nozzles 1, 2 connected to tubes 11, 12. Both liquids join in overflow tank 15 and are drawn into a measuring device and are measured. When the measurement is completed, nozzle 1 is moved into container 10 by a moving mechanism, and at the same time, a valve 20 is opened, the piston of a cylinder 18 is lowered, and cleaning liquid 21 is sucked. Next, valve 20 is closed and valve 23 is opened, and the piston of cylinder 18 is moved up. Then, the cleaning liquid is ejected from nozzle 1, and the substances attached to its end are removed. By this a sample diluter equipped with the function of preventing the clogging of suction nozzoles by solid substances in the sample can be obtained.
