Abstract

A special cleaner is located between a sample cup at the sample absorbing position and a reaction case at the sample delivery position. This cleaner has a V-shaped recess, in which the cleaning liquid is filled in a pile. A pipetting tube is inserted into the sample cup, and a serum sample of the amount corresponding to a plurality of analysis items is absorbed and held by the pipetting tube. The pipetting tube hoisted upward is carried to the sample delivery position. In the process, the pipetting tube passes through cleaning liquid, so that the outer wall of the pipetting tube is cleaned within a short time, thus removing the excessive serum attached to the outer wall. The pipetting tube is lowered into the reaction case associated with the first analysis item to deliver a predetermined amount of serum sample thereinto. The pipetting tube is raised again and the train of reaction cases advances one step so that the tube is inserted into the next reaction case. After the delivery for a plurality of items, the inner and outer walls of the pipetting tube are cleaned.
