Abstract:
1. A method of extracting a liquid phase from a suspension, said suspension including a liquid phase and particles, the method comprising: injecting a suspension into a microfluidic device comprising a main duct, said main duct presenting transverse dimensions lying in the range 10 μm to 10 mm and a longitudinal axis, said main duct including a straight portion; allowing lift forces to develop, in said straight portion, disturbing the flow of said suspension by means of a sudden enlargement of said straight portion thereby forming, downstream said sudden enlargement, extracting, around said recirculation vortex or from the center of said recirculation vortex, a fraction of said suspension that is depleted in particles as a result of said at least one recirculation vortex.
