A nozzle having a length corresponding to the discharge amount of the liquid sample and a diameter capable of storing the liquid sample by the surface tension of the liquid sample is fitted into the small diameter part. At the same time, the pipette is characterized in that its tip part is inserted into the large-diameter part, and the space between the large-diameter part and the nozzle tip part is used as an excess liquid reservoir part. (2) The pipette according to claim 1, wherein the liquid reservoir pipe is detachably fitted into the cylinder. (3) A partition is provided in the large diameter portion of the liquid reservoir pipe at a position separated from the nozzle tip,
The pipette according to claim 1 or 2 of the utility model registration claim, characterized in that the partition has a small hole formed therein to prevent the passage of a liquid sample and allow only air to pass through. .
