Zeta potential measuring cell for measurements on human skin

摘要

One opening respectively of the two bores (3) is located at the flat measuring surface of the body (1). One or more flow ducts (5) are machined in the flat measuring surface of the body (1), between these two openings, in which a laminar flow of the electrolytic liquid results. The surfaces of the supply and discharge duct (3) and/or the flow ducts (5) facilitate no direct electrical connection between the two electrodes (2) located in the ducts (3), so that the ducts (3) or the ducts (5) have a large flow resistance compared to the flow resistance in the remaining flow system.
