Abstract

A fittable pipette tip consists of a vessel which is designed to fit a particularly conical fitting head of a pipette and which may be conical and has a fitting top opening and a bottom opening for receiving and discharging a pipette. A sealing portion with which the pipette tip is adapted to contact the fitting head is spaced from the top end of the pipette tip and is formed with a smooth inside seating surface and has a smaller wall thickness than other portions of the pipette tip so that the sealing portion of the pipette tip is yieldable for adaptation to the fitting head. The pipette tip is reduced in wall thickness at least in the sealing portion by a provision of recesses in the outside and inside surfaces of the wall of the pipette tip.
