PCT No. PCT/EP89/00978 Sec. 371 Date Feb. 21, 1991 Sec. 102(e) Date Feb. 21, 1991 PCT Filed Aug. 19, 1989 PCT Pub. No. WO90/01998 PCT Pub. Date Mar. 8, 1990.A process for producing a thin layer of at least one amphiphilic compound on a carrier is described, in which an at least partially oriented layer of molecules of an amphiphilic compound is produced by compression and expansion at the interface between a fluid and a polar liquid, and a solid carrier is moved through the layer so that the layer is transferred thereto. For this purpose, a directional flow of the polar liquid which contains amphiphilic molecules in solution or as insoluble molecules in a spread form on the surface is generated in an approximately horizontally located channel and the flow is dammed at a barrier which is located at the fluid/polar liquid interface. The flow velocity and, if appropriate, the concentration of the amphiphilic molecules are selected such that a layer of amphiphilic molecules is continuously formed by compression in front of the barrier at the fluid/polar liquid phase boundary. An apparatus suitable for this purpose comprises a horizontally arranged flow channel for taking up a liquid, a barrier arranged at the phase boundary for damming the surface flow in the channel, a device for generating the flow of the liquid and a device for controlled slow immersion of a solid carrier into the channel and emergence therefrom in proximity to the weir.
