    摘要: A microfluidic device that comprises several microchannel structures in which there are an inlet port, an outlet port and therebetween a substructure comprising a fluidic function. The device has an axis of symmetry around which the microchannel structures are arranged as two or more concentric annular zones. for an inlet port and an outlet port of the same microchannel structure the inlet port is typically closer to the axis of symmetry than the outlet port. Each microchannel structure comprises a substructure that can retain liquid while the disc is spun around the axis and/or the inlet ports are positioned separate from the paths waste liquid leaving open waste outlet ports will follow across the surface of the disc when it is spun. For the microchannel structures of an annular zones the corresponding substructures are at essentially at the same radial distance while corresponding substructures in microchannel structures of different annular zones are at different radial distances. The invention also refers to several other substructures. The substructure are primarily adapted for transporting liquid aliquots that have a surface tnsion >5 mN/m with centrifugal force.

    摘要: 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.

    摘要: Process for recovery of zinc and other metal values from zinc waste or other metal waste containing chlorine and/or other anions forming undesirable metal salts. The waste is leached with a liquid organic phase containing a cation exchanger. The impurities are removed from the organic phase with water, and the zinc and other metal values are extracted from the organic phase with mineral acid. Thereafter the zinc and other metal values can be recovered with known methods.
