SFE from 50 ml up to 500 ml

The SFE is versatile "multi-solvent" extraction equipment with precise control of process parameters for analytical purposes :

  • Extraction with supercritical CO2 at pressures up to 1000 bar (15 000 PSI) and temperatures up to 150°C allowing very high pressure extraction over a very wide range of operating parameters and more opportunities to use supercritical CO2 as non-flammable, non-toxic and environment friendly solvent.
  • High pressure and subcritical water extraction up to 400 bar and 250°C.
