Multi-compartment trough

Figure 3.5. (a) Principle of a multi-compartment trough. It contains independent hydro-phobic barriers, enclosing the film. The set-up is such that the films can either be transported (as in fig. (b), compressed or expanded. Redrawn after P. Fromherz, Rev. Set Instnim. 46 (1975) 1380. The drawing is a simplification along the lines of M.C. Petty, W.A. Barlow, in Langmuir-Blodgett Films, ch. 3, G. Roberts, Ed., Plenum, 1980.
