2x Solid State Electrotransport (SSE) (produced by Vacuum praha) is used to refine pure elements (Rare earth metals and uranium) as well as single crystals of intermetallic compounds (mainly prepared by the Czochralski technique).

The SSE technique involves passing a direct electrical current through a metallic rod held between two electrodes. The impurities migrate under the influence of electric filed towards one end of the sample - the purity of the central part of the sample is increased. To prevent the sample contamination (oxidation) the experiment is held under UHV.
Main parts of the apparatus: UHV chamber with pumping system, a direct current source.
