Title
(EN) MICROFLUIDIC FLOW DEVICE HAVING AT LEAST ONE CONNECTING CHANNEL LINKING TWO CHANNELS AND CORRESPONDING METHOD FOR USING SAME
(FR) DISPOSITIF D ' ECOULEMENT MICROFLUIDIQUE AYANT AU MOINS UN CANAL DE LIAISON RELIANT DEUX CANAUX ET PROCEDE DE MISE EN OEUVRE CORRESPONDANT
Abstract
(EN)
The invention concerns microfluidic flow device comprising: at least one flow channel (A), emerging into a bypass (D), whereto are connected at least two outflow channels (B, B'), and at least one connecting channel (BL) linking the two outflow channels, the connecting channel emerging onto each outflow channel in a short-circuit point (PCC, PCC') which is preferably located at less than half the length of each outflow channel (1 < L/2; 1' < L'/2).
(FR)
Ce dispositif d'écoulement microfluidique comprend : - au moins un canal d'écoulement (A), débouchant dans une dérivation (D), à laquelle sont liés au moins deux canaux dérivés (B, B'), et - au moins un canal de liaison (BL) reliant les deux canaux dérivés, - le canal de liaison débouchant sur chaque canal dérivé à un point de court-circuit (PCC, PCC') qui est situé de préférence à moins de la moitié de la longueur de chaque canal dérivé (1 < L/2; 1' < L'/2.
