Abstract: The invention relates to a microfluidic apparatus for producing a volume flow that is uniform over time in a metering process. In various solution processes or reaction processes it is essential to have a specified given volume flow or mass flow of fluid available to ensure reliable dissolution of the reagent or ensure that the reaction takes place. In microfluidic apparatus in which separation of particles from a fluid, particularly blood, is carried out through a membrane, the volume flow through the membrane decreases continuously. In order to achieve a uniform volume flow during metering, it is envisaged that first of all a reservoir is filled from a first channel, so that the contents of the reservoir can then be fed to the metering process by opening a fluid stop. The emptying of the reservoir takes place with a uniform volume flow of 0.05 microliters per second to 10 microliters per second.
