Abstract
In order to continuously produce an ultrathin, ordered layer of amphiphilic molecules on the surface of a polar liquid a directed flow of the polar liquid is produced in a duct which contains the amphiphilic molecules in dissolved or undissolved form on the surface in spread form. In the duct, a duct section having a relatively high flow rate on the surface and comprising a ramp which is arranged at the bottom of the duct and washed over by the polar liquid is provided. This is followed by a duct section having a relatively low flow rate on the surface, in which the flow is dammed up at an obstacle at a liquid level constant with time, so that an ultrathin, ordered layer of amphiphilic molecules is continuously formed in these duct sections at the polar liquid/air interface by compression of the flow. The washed over ramp is movable.
