Abstract:
1. A pipette tip having the shape of an elongate tube with a lower opening ( 4 ) at a lower end ( 3 ) for the passage of liquid, and an upper opening ( 6 ) at an upper end, wherein a seat area ( 30 ) exists on an inner circumference contiguous to the upper opening ( 6 ), which serves for plugging it onto a conical attachment piece ( 37 ) of a pipetting device ( 30 ), wherein the seat area ( 30 ) has a retaining area ( 11 ) with axially extending ribs ( 12 ) projecting radially towards the inside from the inner circumference of the head portion, and below the retaining area ( 11 ) a sealing area ( 19 ) and is configured such that when the pipette tip ( 1 ) is plugged onto the attachment piece ( 37 ) with its seat area ( 30 ) by a plugging force which ensures retaining and sealing of the pipette tip ( 1 ) on the attachment piece ( 37 ), the ribs ( 12 ) are partly plastically deformed, and elastic deformation occurs in the seat area ( 30 ) outside of the ribs ( 12 ).
