A microfluidic device for the splitting or sequencing of fluid flow includes a plurality of upstream and/or downstream chambers coupled via microfluidic channels. For splitting fluid, a substrate is provided that includes a main chamber and a plurality of downstream sub-chambers. Each sub-chamber is associated with a sealable vent hole. Fluid is selectively moved into the desired sub-chamber of interest by unsealing its associated vent hole. Fluid is then pumped into the sub-chamber, for example, by rotating the substrate. For flow sequencing, a substrate is provided that includes a plurality of upstream chambers coupled to at least one downstream chamber. Each upstream chamber has an associated vent hole that can be selectively opened. The substrate is then rotated and fluid contained in the upstream chamber with the valve in the unsealed state will then pass to the at least one downstream chamber.

Cette invention concerne un dispositif microfluidique pour le fractionnement ou la mise en séquence d'un écoulement fluidique, comprenant une pluralité de chambres amont et/ou aval couplées via des canaux microfluidiques. Le fractionnement de fluide s'opère au moyen d'un substrat comprenant une chambre principale et une pluralité de chambres secondaires en aval. Chacune de ces chambres secondaires est associée à un orifice d'évent obturable. Pour faire passer sélectivement le fluide dans la chambre secondaire d'intérêt choisie, on ouvre l'orifice d'évent correspondant. On pompe alors le fluide dans la chambre secondaire, par exemple en faisant tourner le substrat. Pour la mise en séquence du flux, on utilise un substrat qui comprend une pluralité de chambres amont raccordées à au moins une chambre aval. Chaque chambre amont est assortie d'un trou d'évent qui peut être ouvert sélectivement. On fait ensuite tourner le substrat pour que le fluide contenu dans la chambre amont avec la soupape en positon ouverte passe dans au moins une chambre aval.
