Abstract
A manual pipette includes a manual volume adjustment having three discreet resolutions. The pipette uses three rotatable step cylinders and one non-rotatable cylinder to set the overall stroke length for the piston. The step cylinders are rotated by manual dials that are accessible on either side of the pipette body. The dial bodies include numerical scales corresponding to the setting of the respective step cylinders.
