Abstract: An electrophoretic separation device includes an anode and a cathode, a porous scaffold material, and a liquid separation medium, wherein the separation medium is located inside the porous scaffold material, is in contact with the cathode and the anode, and has been applied to the porous scaffold material in form of a custom-made geometrical shape defining a migration path for a biomolecule-containing sample, wherein the sample is enclosed by the separation medium.

Abstract: An apparatus for determining the volume fractions of the phases in a suspension includes a body, a channel structure, which is formed in the body, and an inlet area and a blind channel, which is fluidically connected to and capable of being filled via the same. Furthermore, a drive for imparting the body with rotation, so that phase separation of the suspension in the blind channel takes place, is provided. The blind channel includes such a channel cross-section and/or such wetting properties that, when filling same via the inlet area, higher capillary forces act in a first cross-sectional area than in a second cross-sectional area, so that at first the first cross-sectional area fills in the direction from the inlet area toward the blind end of the blind channel and then the second cross-sectional area fills in the direction from the blind end toward the inlet area.
