Abstract
A hand-held electronic pipettor is designed particularly to be programmed and operated with one hand for the convenience of the user. It uses a capacitance touchpad control for programming, and a separate run button for the operating mode. Internal components are located so that the center of gravity of the pipettor is located within the palm of the user. Flash memory stores an empirically derived table that correlates aspiration volume to motor steps and a separate empirically derived table the correlates dispensing volumes to motor steps.
