Abstract:
1. A device for taking up liquid from a vessel having a bottom with a curved surface, the device comprising a removal unit having a removal tip formed as a channel surrounded by a wall, the removal tip having at its end an end surface defined by the surrounding wall, wherein the removal tip or the vessel bottom is configured or arranged relative to each other such that an area of the surface of the vessel bottom on which the removal tip would touch down, when the removal tip is inserted into the vessel, and an area of the end surface of the removal tip are tilted relative to each other at least in one portion of the two surface areas, such that the two surface areas are not parallel at the tilted portion, and wherein the removal tip is arranged eccentrically to an apex of curvature of the vessel bottom surface, such that when the removal tip touches down on the vessel bottom there will always result a gap between the at least one portion of the surface area of the vessel bottom and the end surface area of the removal tip, so that the removal tip is prevented from suctioning to the vessel bottom and the liquid flows through the gap into the removal unit.
