ABSTRACT:
An adjustable hand-held pump adapted to measure microliter quantities of liquids includes a frame having a handle with a cylindrical opening formed therein. A threaded shaft is disposed and slidable within the cylindrical opening. A volume adjustment wheel is rotatably disposed within the frame at a stationary axial position and mechanically engages the threaded shaft to position the threaded shaft at a predetermined axial position within the cylindrical opening, thereby providing liquid volume adjustment.
