Title:
VALVING SYSTEM FOR USE IN CENTRIFUGAL MICROFLUIDIC PLATFORMS
Document Type and Number:
WIPO Patent Application WO/2014/086956
Kind Code:
A3
Abstract:
The invention relates to 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.
