The invention relates to liquid dispensing and concerns a multichannel pipette, which comprises on its lower tip (4) a shelf in the transverse direction of the tip and to which lower tip a pipette tip (5) can be attached, which pipette tip comprises at least one longitudinal claw (8), whereby when the pipette tip is in its place, the point of the claw is above the shelf. Each cylinder is connected with a claw opening comprising an opener (9) so that by pressing the opener downwards the claws can be turned outwards off the shelf. The opening mechanism further comprises an organ (10) resilient in the longitudinal direction. In accordance with the invention, the tip removal is made to function reliably, even if there were significant differences in the dimensioning of the opening constructions of the lower tips.
