Beschreibung
Zusammenfassung:	The invention relates to a method for increasing the metering precision of microfluidic pumps and valves based on a flexible cover film/membrane and a valve trough, in which the surface of the membrane, which faces the valve trough, is heated using a laser beam. L'invention concerne un procédé pour augmenter la précision de dosage de pompes et vannes microfluidiques faisant appel à une membrane/un film de recouvrement flexible et à un puits de vanne, procédé selon lequel la surface de la membrane qui fait face au puits de vanne est chauffée par un faisceau laser.
