摘要
A top part for a sampling pipette including a hollow outer body forming a handle, a pipetting control stem, a device for adjusting and displaying a volume to be sampled, including a first threaded member for adjusting the volume to be sampled crossed by the control stem, the device also comprising a set of first volume graduations angularly spaced from one another around the longitudinal axis and cooperating with a first mark so as to inform about the volume to be sampled. The first threaded member is rotatably integral with one of both elements formed by the set of first volume graduations and the first mark, the mark being axially arranged between the hollow outer body forming a handle and the control knob.
