Abstract
A method for determining a volume of liquid is described, wherein the liquid is drawn from a vessel by means of a pipette or is delivered from a pipette into a vessel, respectively. In particular a method is described, wherein as the first step the volume of liquid contained in a vessel V is determined by a detector means. Then a volume of liquid V is drawn into a pipette and, subsequent thereto, the volume of liquid contained in the vessel V is determined again. Thereafter the volume of liquid actually drawn off V is calculated in accordance with the equation V −V =V . Subsequent thereto the difference between the volume of liquid actually drawn off V and a volume of liquid predetermined to be drawn off V is calculated in accordance with the equation |V −V |=V . Then a comparison of the difference V with a predetermined volume of liquid &egr; is conducted and an error message is displayed in case V >&egr; .
