Title
(EN) MICRO-FLUIDIC SYSTEM
(FR) SYSTÈME MICROFLUIDIQUE
Abstract
(EN)
A micro- fluidic system (1) comprising a micro-fluidic channel (2), which has a wall (7) provided with a hole (9), within which a closing portion (16) of a closing element (13) extends; when the closing portion (16) is arranged within the micro-fluidic channel (2), the passage of the liquid along the channel (2) is interrupted; by deforming the closing element (13) by suction the closing portion (16) may be lifted and therefore allow the passage of liquid along the micro-fluidic channel (2).
(FR)
L'invention concerne un système microfluidique (1) comprenant un canal microfluidique (2), équipé d'une paroi (7) dotée d'un trou (9), dans lequel s'étend une partie de fermeture (16) d'un élément de fermeture (13); quand la partie de fermeture (16) est disposée dans le canal microfluidique (2), le passage du liquide le long du canal (2) est interrompu; en déformant l'élément de fermeture (13) par aspiration, la partie de fermeture (16) peut être levée et permet donc le passage de liquide le long du canal microfluidique (2).
