    • A micromechanical pipetting device comprising an integrally built pipetting module which has an inlet/outlet which may be connected to a removable pipetting tip or integrally built with a pipetting tip. The pipetting module comprises a micromechanical structure which is integrally built on a silicon wafer. In order to improve the accuracy of the pipetted volume the device is characterized in that it comprises a) a first chamber located within said pipetting module, the volume comprised within said first chamber being alterable by displacement of a membrane which is a portion of a wall of said chamber, said first chamber having an opening, said opening being permanently open and allowing fluid flow into and from the interior of said first chamber, b) a channel located within said pipetting module, said channel establishing a direct, valveless and permanent fluidical connection between said opening of the first chamber and the inlet/outlet of the pipetting module, c) actuator means for displacing said membrane, and thereby aspiring or expelling a volume of air or of a liquid into or from said first chamber, which in turn causes aspiring or expelling a volume of a liquid sample into respectively from said pipetting tip, and d) first sensor means for generating a first output signal related to the displacement of the membrane.

    • A method and a micropipetting apparatus is described for dispensing a liquid volume into a vessel via pipetting needle without any contact between the needle and a liquid contained in the vessel. The method comprises forming a drop at the delivery tip of the pipetting needle, the drop being retained at the tip by adhesion forces, and ejecting the drop from the tip of the pipetting needle by focusing at the tip of the pipetting needle a mechanical excitation wave applied at an excitation point at some distance from the tip of the pipetting needle. The apparatus comprises a pipetting needle, an electromechanical transducer mechanically connected with said pipetting needle for mechanically exciting the pipetting needle with a pulse of mechanical waves that propagate through the needle, and an electrical signal generator for generating an excitation pulse signal and for applying this signal to the electromechanical transducer.
