ABSTRACT:
A microfluidic device which comprises two or more microchannel structures (set1), each of which comprises a structural unit which comprises (i) one or more inlet microconduits, and (ii) an outlet microconduit 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 in said two or more microchannel structures is a restriction microconduit. There may also be a microcavity between the inlet microconduit(s) and the restriction microconduit in each microchannel structure. Typically common flow 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 to the microchannel structures of the device.
