Abstract : We present an experimental setup dedicated to the caracterisation of the interfacial layers formed by adsorbed biomolecules at fluid interfaces. The setup is an null ellipsometer and a Brewster Angle Microscope. Additionnaly, the evaporation of the solution is counterbalanced by an apport of water, regulated with the weight of the solution. Furthermore the surface tension is measured simultaneously by a commercial device. The setup is developped to measure continuously the adsortion kinetics during many tens of hours, which requires that no interruption occurs during this time. This device brings informations on the behaviour of biomolecules at hydrophilic-hydrophobic interfaces, as foam bubbles surfaces or biological membrane surface.
