Abstract

Official abstract text for this publication.

A device for preparing a solution from a sample and a reagent, the device includes a microfluidic array having a sample supply inlet, a reagent supply inlet, a discharge outlet, a solution collection outlet, a sampling zone to which the inlets are connected, first and second preparation chambers connected to the sampling zone, arranged to either side of the sampling zone such that the liquid flowing from one preparation chamber to the other flows through the first sampling zone, the first preparation chamber having a volume that is variable between a minimum volume and a calibrated volume. The device includes valves interrupting the flow of the fluid at least at the two inlets and the collection and discharge outlets.
