The aim of the present work was the study of flow phenomena of chosen Stokes fluids in the plate and sinusoidal shape channels of two various types. The first of them had the regular shape and the second one was characterized by the opponent walls displaced in the phase. The constructions of this type can be applied in processing and biotechnology where the media very often have the non-Newtonian character and the laminar flow is required. Mass transfer coefficients in modified channels observed were greater than these ones measured in the plate exchanger. The best effect was obtained for the sinusoidal channel of symmetric construction.
