Patent ID: 8084004

Claim:
A microfluidic arrangement, for metering first metered amounts of liquid (A) and for separating the latter from a second amount of liquid (B) via a gaseous phase, comprising: a first channel and second channels; the first channel has one inlet and one outlet; in the area of the outlet, the arrangement has a capillarity, which is greater than or equal to the capillarity in the area of the inlet, whereby the capillarity moves an amount of fluid in the first channel from its inlet to its outlet; each second channel branches off from the first channel at a branch point, the branch points located sequentially along the first channel; each of said second channels provided with an outlet; each second channel having a predetermined volume forming an individual and discrete fluidic flow path with an individual fluidic outlet; the second channels have a greater capillary force than the first channel at the branch points; a plurality of third channels each provided with an inlet and outlet, each of said third channels situated downstream from one of said second channels; a stopping means provided between the outlet of each of said second channels and the inlet of each of said third channels; and said first channel, said second channels and said third channels all provided on the same planar surface.
