    摘要: The present invention is to present a disposable pipette tip that can easily prevent a tight fit with another pipette tip without providing a separating mechanism in a supplying apparatus. The disposable pipette tip comprises: an attachment section for being attached to the dispensing device; and a liquid containing section for containing a liquid aspirated by the dispensing device, which is continually located to the attachment section, has a tapered distal end and comprises a tight fit preventing part which is located adjacent to the tapered distal end and prevents a tight fit with another pipette tip.

    摘要: The present invention is to present a disposable pipette tip used in a dispensing device, comprising: an attachment section for being attached to the dispensing device; and a liquid containing section for containing a liquid aspirated by the dispensing device, which is continually located to the attachment section and comprises a first part and a second part being continually located to the first part on the attachment section side, wherein the first part comprises a tip portion, an intermediate portion and a stepped portion, the tip portion including a distal end of the pipette tip, the intermediate portion continually located to the tip portion and the second part, the tip portion having an external diameter that decreases toward the distal end, and the intermediate portion having an external diameter that decreases toward the tip portion; the stepped portion is formed at a connecting position of the tip portion and the intermediate portion such that the external diameter of the intermediate portion at the connecting position is larger than that of the tip portion at the connecting position, the connecting position being closer to the distal end than the second part; the second part has an internal diameter that decreases toward the first part; the external diameter of the intermediate portion at the connecting position is larger than the internal diameter of an end of the second part on the first part side; the external diameter of the tip portion at the connecting position is smaller than the internal diameter of the end of the second part on the first part side; and length from the end of the second part on the first part side to the end of the attachment section on the opposite side of the second part is not less than twice but not more than four times as large as that of the tip portion.
