Abstract
A microfluidic device comprising a flow channel with an inlet and a gas escape opening is described. The flow channel comprises a liquid flow channel section and a flow controlling section downstream to the liquid flow channel section and upstream to or coinciding with the gas escape opening. The flow controlling section provides a flow resistance to gas, which is sufficiently high to reduce velocity of a capillary flow of a liquid in the liquid flow channel section.
