Abstract
The invention relates to a method for increasing the dosing precision of microfluidic pumps and valves based on a flexible cover film/diaphragm and a valve trough, in which the surface of the diaphragm facing the valve trough is heated with a laser beam.
Claims21
A method for increasing the dosing precision of microfluidic pumps 1, 2, 3 or valves which have a flexible diaphragm (4) and a valve body (8) with at least one valve trough (5, 6, 7), the flexible diaphragm (4) being attached to the valve body (8) in order to cover the valve trough (5, 6, 7), wherein the surface (9) of the diaphragm (4) facing the valve trough (5, 6, 7) is heated with a laser beam.
