Abstract
The invention concerns a device which is used to separate gas or liquid from microfluidic flow-through systems. The gas or liquid separation is achieved independently of the spatial orientation of the device. In addition the invention concerns a microfluidic flow-through system in which a device according to the invention enables bubble-free fluid transport.

23. A microfluidic device for separating liquid and gaseous phases in a microfluidic flow-through systems which can be operated independently of its orientation comprising:
-
a hollow body connected to the microfluidic flow-through system such that the liquid to be transported is conveyed through the hollow body;
wherein the hollow body comprises an inlet opening and outlet opening for feeding in and discharging the liquid;
wherein the inlet opening and the feed outlet opening are connected to a feed tube, wherein the feed tube extends into a hollow space of the hollow body; and
wherein the feed tube at the inlet opening protrudes into the interior space of the hollow body such that it prevents a direct flow from the inlet opening to the outlet opening. - View Dependent Claims (24, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
