MIKROFLUIDISCHE ANORDNUNG ZUM DOSIEREN VON FLÜSSIGKEITEN

摘要

The micro-fluid assembly to give a dosed delivery of volumes of one fluid, separated from a second fluid volume, has a first channel (2) with an inflow (11) and outflow (12) and one or more second channels (6-8) in a second channel structure (16). The micro-fluid assembly to give a dosed delivery of volumes of one fluid, separated from a second fluid volume, has a first channel (2) with an inflow (11) and outflow (12) and one or more second channels (6-8) in a second channel structure (16). The capillary force at the first channel outflow is equal to or greater than at the inflow. The second channels are linked to the first channel at a junction (4), with a greater capillary force than the first channel at the junction. The first fluid travels along the first channel from the inflow to the outflow, and a portion enters the second channel at the junction to fill it completely, leaving the remainder to pass through the outflow. The fluid volume in the second channel assembly is separated by a gas from the remaining fluid in the first channel, after the second channels have been filled.
