Abstract

PURPOSE:To maintain the accuracy of dispensing for a long time and simplify hardware by employing a squeezing pump for a pump for deliverying diluting liquid. CONSTITUTION:Diluting liquid is kept filled in a piping system by deliverying the diluting liquid in a diluting liquid vessel 7 to a pipeline Ta by rotating a pump 10 counterclockwise. After it is filled, the squeezing pump 10 is stopped. If a dispensing nozzle 4 is inserted into the vessel 1, and a syringe 5 for distribution is operated to make suction, the sample 2 in the vessel 1 is sucked. Thence, the nozzle 4 is moved to the side of a vessel 3 to be dispensed and the syringe 5 is operated to make discharging. At the same time, the pump 10 is driven counterclockwise. The sample 2 in the nozzle 4 is discharged into the vessel 3, and while the remaining liquid sample in the nozzle 4 is being washed out by the diluting liquid delivered by the driving of the pump 10, it is discharged together with said diluting liquid into the vessel 3.
