ABSTRACT:
It is an object to provide an apparatus adaptable to an apparatus for analyzing liquid samples in the chemical field or the biochemical field, and capable of performing pretreatment, such as washing of the needle and diluting of the collected sample. The pretreatment apparatus comprising: a needle for sampling at least a liquid sample in a predetermined quantity which must be pretreated; a needle holding mechanism for movably holding the needle in a vertical direction; a frame for movably holding the needle holding mechanism in a horizontal direction; a needle washing block which is provided for the needle holding mechanism, which is capable of moving in the horizontal direction together with the needle and the vertical movement of which is inhibited; a pretreatment tank formed by integrating a diluting tank for diluting the liquid sample and a liquid discharge tank for discharging waste liquid; a mixing fluid passage for mixing the diluted liquid sample; and pipes and at least two syringes for defining flow passages connecting the needle, the needle washing block, the pretreatment tank, and the mixing fluid passage.
