PROBLEM TO BE SOLVED: To provide a pipette tip which does not need a strong power for connecting or taking off.SOLUTION: The pipette tip 1 has the shape of an elongate small tube with a lower opening at the lower end for the passage of liquid, and an upper opening 6 at the upper end. A seat area 30 exists on the inner circumference adjacent to the upper opening 6. The seat area 30 serves for plugging it onto a standardized conical attachment piece of a pipetting device. The seat area 30 has a retaining area with the first ribs 12 projecting radially toward the inside and axially extending. Below the retaining area, a sealing area is configured such that when the pipette tip is connected to the seat area by a connection force which ensures retaining and sealing of the pipette tip on the attachment piece, the first ribs 12 are partially elastically deformed, and elastic deformation occurs in the seat area 30 outside the first ribs 12. |
