Abstract
The invention is a pipette controller for facilitating the handling of liquids by a pipette. The pipette attaches to the pipette controller. The pipette controller has a handle which is proximate to the attached pipette and substantially parallel to the pipette. The user operates the pipette controller by working a thumb wheel on the handle which is mechanically coupled to a bellows which controls the liquid level in the attached pipette. When operating the pipette controller, the user grasps the hand below the thumb wheel at a position which is approximately medial to the length of a typical pipette.
