N1 - Funding Information:
We would like to thank our summer student F. Richter for his support in the lab. K. Brakke’s support on tricky Surface Evolver issues has been invaluable. This work benefited significantly from discussions with F. Graner, R. Seemann, S. Herminghaus, I. Cantat, R. Delannay, J. Osing and I. Shvets. Above all we would like to thank S. Hutzler and F. Elias for getting the ball rolling in the direction of Discrete Microfluidics. We are grateful for financial support from the Ulysses France-Ireland Exchange Scheme and the European Space Agency, Contract 14308/00/NL/SH (AO-99-031) CCN 002 MAP Project AO-99-075. W. Drenckhan was funded by the German National Merit foundation, G. Delaney by a Trinity College Award, and N. Kern by a Marie Curie European Fellowship (HPMF-CT-000-01079).

N2 - Microfluidics is a rapidly developing field of innovation, which provides the chemical, medical and (bio)pharmaceutical industries with a much more efficient substitute for the use of well plates, syringes, etc., to perform multiple manipulations and analysis of small samples. While conventional, continuous microfluidics and the manipulation of individual nano-droplets in "Digital Microfluidics" are highly advanced, a major new dimension is added by our work on the flow of ordered foam and emulsion structures in specifically designed channel geometries. We show experimentally and computationally, utilizing both the quasi-static and Viscous Froth models, how the interplay between channel geometry and ordered foam/emulsion structures can be used to process tiny amounts of gases or liquids in a highly reliable and efficient way. We have termed this method "Discrete Microfluidics" and will introduce its various aspects in this paper.
