Abstract
A pipette tip for and method of automatically maintaining pipette tip depth in a fluid during a fluid transfer operation is disclosed. The pipette tip includes, for example, two electrodes that run substantially the full length of the pipette tip for measuring the resistance therebetween when submerged in a conductive fluid. A method is provided of automatically maintaining the depth of the pipette tip in a liquid throughout a pipetting operation, as the liquid surface rises or falls in its container, without any prior knowledge of the container geometry.
