Abstract

A microfluidic system for processing biological samples comprising a holding chamber adapted for holding a fluid and to be rotated on a platform, said holding chamber comprising an outlet through which fluid flow is controlled by an acceleration-primed valve system, wherein the acceleration-primed valve system comprises a capillary valve and an outlet channel. The invention provides a novel valving system, which retains fluids at low angular velocities, removes the need for hydrophilic surfaces, minimises disc real-estate and optimises certain microfluidic processes done in the holding chamber.
