Apparatus to determine the electrokinetic potential and permeability of membrane materials has holder bodies flanking the membrane forming a sealed flow channel

摘要

The apparatus to determine the electrokinetic potential and the permeability of a membrane has at least two bodies forming the membrane holder, and a section to form a flow channel. The flow channel is sealed against the outside environment by sealing rings. The apparatus has at least two electrodes flanking the membrane, in contact with the flow medium.
