The interfacial tension between two liquids is determined by: flowing an internal liquid (L) through an internal flow member () and flowing an external liquid (L) through an external flow member (), with conditions being first established such that either droplets (G) of the internal liquid are formed in the external liquid, or a continuous jet of the internal liquid is formed in the external liquid, the continuous jet of the internal liquid then being formed in the external liquid or droplets of the internal liquid then being formed in the external liquid, and deducing therefrom the value of the interfacial tension between these two liquids.

Method and apparatus for determining the interfacial tension between two liquids

Operation of a microfluidic flow device includes providing a microfluidic flow device including a body and at least one flow microchannel for transferring a mixture (G; T') of at least two components being formed within the body, in which said mixture (G; T&#x2032;) of the at least two components is caused to flow in the flow microchannel and the mixture is analyzed in at least one derived branch (B-B).

Microfluidic flow devices for determining parameters of physical and/or chemical transformations

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.
