We focus here on the transfer and concentration of macromolecules from a flowing carrier fluid to a storage liquid. These liquids are flowing in parallel channels, separated by interfaces sustained by micro-pillars. The two fluids should not mix. The best efficiency of such devices is obtained for a largest possible interfacial surface. However, it is observed that, for a given geometry of the pillars, there are only a limited number of interfaces that are stable. In this work, we investigate the stability of the interfaces and deduce some recommendations for improving their stability
