There is disclosed a device for handling liquid samples, said device comprising: a) projections substantially perpendicular to the surface of said device, said projections having a height, diameter and a distance between the projections capable of generating capillary flow, lateral to said surface, of a fluid, b) at least one zone for receiving a sample, c) at least one sink with a capacity of receiving said liquid, said at least one sink exerting at least two different capillary forces on said liquid, d) at least two flow paths connecting said at least one zone for receiving a sample and said at least one sink, said flow paths exerting at least two different capillary forces on said liquid, e) at least one connection between said at least two flow paths.

L'invention concerne un dispositif pour la manipulation d'échantillons de liquide, ledit dispositif comprenant : a) des protubérances sensiblement perpendiculaires à la surface dudit dispositif, lesdites protubérances ayant un hauteur, un diamètre et une distance entre les protubérances aptes à générer un écoulement capillaire d'un fluide, latéralement par rapport à la dite surface, , b) au moins une zone de réception d'un échantillon, c) au moins un puits ayant la capacité de recevoir ledit liquide, ledit au moins un puits exerçant au moins deux différentes forces capillaires sur ledit liquide, d) au moins deux trajets d'écoulement reliant ladite au moins une zone de réception d'un échantillon et ledit au moins un puits, lesdits trajets d'écoulement exerçant au moins deux différentes forces capillaires sur ledit liquide, e) au moins une connexion entre lesdits au moins deux trajets d'écoulement.
