Abstract

This invention relates to a microchannel device comprising a microchannel and a liquid introduction means for introducing at least two liquids into the microchannel; characterised in that the introduction means comprises a pulse means for introducing each liquid into the microchannel in the form of a plurality of pulses, and for staggering the pulses of each liquid relative to the pulses of the other liquids. The device may be used to mix liquids for microfluidic applications.
