Heinrich Schnitger constructed in the spring of 1957 in cooperation with the mechanical workshop of the Institute for this work a novel device with which it was possible to dispense small amounts of fluid quickly and precisely by hand. In the same year he presented under the title "A rapid and precise pipetting of small liquid quantities" a patent at the German Patent Office one, issued in 1961. The company Eppendorf improved the first "Marburg pipette" sold apparatus in cooperation with Heinrich Schnitger on and took over the exclusive license of the patent for commercialization.
