METHOD FOR INCREASING THE METERING PRECISION OF MICROFLUIDIC PUMPS OR VALVES AND WELDING DEVICE AND TENSIONING DEVICE FOR CARRYING OUT THE METHOD

摘要

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.
