Abstract

A centrifugal-based microfluidic device (1) that comprises a hydrophilic microchannel structure (2) in which there is a A capillary valve I (24) is associated with microconduit I (17). The flow direction through liquid outlet I (6) is directed upwards and/or liquid outlet I (6) is placed in a downwardly turned part of an inner wall of the separation microcavity (4), and/or the part of microconduit I (17) next to liquid outlet I (6) is directed upwards.
