Abstract
A microfluidic flow device includes at least one flow channel flowing into a branch point, to which at least two branched channels are connected, and at least one linking channel interconnecting the two branched channels. The linking channel flows into each branched channel at a short-circuit point which is preferably located at less than half of the length of each branched channel.
Claims21
A microfluidic flow device comprising:
- at least one flow channel flowing into a first branch point to which at least two branched channels are connected, said branched channels having respective lengths, and
- at least one linking channel interconnecting the two branched channels,
- the linking channel flowing into each branched channel at a respective short-circuit point located intermediate the ends of respective lengths of the branched channels at less than half of the length of each branched channel starting from the first branch point,
- at least one of the branched channels of the first branch point flowing into a second branch point to which at least two branched channels are connected, the branched channel extending between the two branch points constituting a branched channel of the first branch point and a flow channel of the second branch point.
