A rotatable microfluidic device that comprises a hydrophilic microchannel structure in which there is a) an upstream microcavity I with a liquid outlet I, b) a microconduit I connected to liquid outlet I, and c) a capillary valve I associated with microconduit I. The inlet end of the microconduit is closer to the spin axis than the outlet end of the microconduit. The difference in radial distance between the inlet end and the outlet end of microconduit I is typically &#x2267;5%, such as &#x2267;10% or &#x2267;100% or &#x2267;500%, of the difference in radial distance between the uppermost part of the upstream microcavity and liquid outlet I.

Liquid plugs

A microfluidic device comprising a hydrophilic microchannel structure in which there is a functional unit that comprises a microconduit which a) is intended for the transportation of liquid aliquots, and b) has an inlet end and an outlet end between which there is a capillary valve I, which preferably is based on the presence of a local non-wettable surface area. Microconduit I further comprises one or more additional capillary valves, typically one. At least one of the additional valves is upstream of capillary valve I, such as at the inlet end of the microconduit.

Microfluidic device with serial valve

The invention relates to a method for capturing charged molecules of interest traveling in an electrolyte flow stream through an electrically non-conductive channel, comprising at least one anode and at least one cathode individually separated from said channel, but in electrical contact with said flow stream, by a conductive ion selective semi-permeable membrane. Said membrane interferes with the normal migration of ions towards its respective electrode, generating at least two zones of different electric field. Balance between hydrodynamic and electrical forces captures certain ions into the flow stream. it also relates to a device for performing the method.

Method for capturing charged molecules traveling in a flow stream

A method for dispensing droplets of a liquid to a microsystem in the form of a disc comprising a target area (TAI) in its surface, said disc preferably being a microfluidic disc comprising a microchannel structure with an inlet port that is a target area (TAI). The method is characterized by comprising the steps of: The invention also comprises the dispenser arrangement as such.
