A trough for the formation of a monomolecular layer of an organic film on a frame preferably having top and bottom separable frame portions. A plate is disposed within the frame and is formed of a rigid substance. A sealing element of chemically inert material is positioned between the top of the plate and the top frame portion and preferably comprises a perfluoroelastomeric material that is conformable to the top of the plate and to the top frame portion to prevent subphase leakage from the trough. Apparatus is provided for laterally compressing a layer of amphipilic solution deposited on the subphase to form a solid monomolecular film. The apparatus includes a movable barrier dimensioned to rest to superposed relation on the plate. An additional sealing element of chemically inert material may be spaced adjacent to the above-mentioned sealing element, and also positioned between the top of the plate and the top frame portion for cooperating with the above-mentioned sealing element to prevent the subphase from reaching the frame.
