We have studied the transfer of a surfactant covered film between two Langmuir troughs over a bridge-shaped glass slide when the surfactant concentrations in the two troughs were maintained at different values. We applied the Landau-Levich theory to this problem, assuming the Deryagin-Landau disjoining pressure for water films on glass. The theoretical relationship between the rate of transfer and the surface pressure differential in the two troughs is in good agreement with the experiment.
