Patent attributes
A liquid router that comprises an inlet microconduit that branches into two exit microconduits (microconduit I and II) and is present in a microchannel structure of a microfluidic device which is using centrifugal force created by spinning the device about a spin axis for transporting liquid. The router is characterized in comprising a microcavity in which there are: a lower part comprising two exit openings (exits I and II), and an upper part comprising an inlet opening to which the inlet microconduit (3) is connected, and microconduits I and II which are connected to exits I and II, respectively, and stretch from a shorter radial position to a larger radial position relative to the spin axis. Microconduit II has a reduced hydrophilicity (=reduced apparent wettability) compared to microconduit I.
