Abstract
A method for washing a U-shaped reaction tube having a thick cup portion and a thin non-cup portion is disclosed. At a first washing position, a washing liquid is supplied into the cup portion of reaction tube like a shower and is simultaneously sucked via the non-cup portion of reaction tube. Then, the washing liquid is supplied again into the reaction tube to fill the tube therewith at a second washing position. Finally, at a third washing position, the washing liquid contained in the reaction tube is drained at such a relatively slow rate that the liquid level of the washing liquid descends slowly. Any drop of the washing liquid is not remained on the inner wall of test tube, and thus it is possible to effect a highly accurate analysis without being affected by contamination between sample solutions.
