A micro fluidic device which comprises two or more micro channel structures (201.301) (set 1), each of which comprises a structural unit which comprises (i) one or more inlet microconduits (102,103,202,203, 302,303), and (ii) an outlet microconduit (105,205,305) downstream said one or more inlet microconduits, and (iii) a flow path for a liquid passing through either of said inlet microconduits and said outlet microconduit. The device is characterized in that each outlet microconduit (105,305) in said two or more microchannel structures (201,301) is a restriction microconduit (105,205,305 ). There may also be a microcavity between the inlet microconduit(s) and the restriction micro conduit in each microchanel structure. Typically common fl ow control is used for driving a liquid flow within the device. The innovative design is useful for creating flow with low inter-channel variation with respect 15 to the microchannel structures of the device.
