Claims

[Scope of utility model registration request]

In a micropipette in which a tip is removably inserted into the pipette body, the tip of the pipette body has a wedge-shaped inward claw at the free end of the tip, and a plurality of axially extending tips whose bases are fixed to the pipette body. a book tip stopper and a pusher which moves up and down in the axial direction and expands the inward claws of the tip stopper in its lowered position;
A micropipette is provided with a circumferential groove in which the inward claw of the tip stopper engages.
