FISCHER® EMS - 250 / SR  Laboratory Mixer / Settler - Extractor

For liquid-extraction according to the Mixer-Settler-principle, design according to Dr. E. Müller (Lurgi).


With screw stirrer for intensive mixing of the phases, especially suited for metallic salt extraction. Pumping capacity and residence times are changed by adjusting the stirrer speed. An additional advantage of the unit is the application for extractions during which reactions of considerable density changes occur.


Typical application for this universal appartaus are:

  • metal salt extractions
  • mixtures with low surface tension
  • if the dispersed phase coalesces with difficulty
  • if variation in residence time of the phase occur in the extraction stages
  • if considerable changes in density are expected as a result of extraction


Extraction parameters determined by this unit can be scaled up.

All parts in contact with the product are made of borosilicate glass 3.3 and PTFE. Once adjusted, the Mixer-Settler-Extractor works maintenance-free and can be switched on or off without changing the hydrodynamic conditions.
