Subcritical Water System

SHARE

Our laboratory extraction equipment using supercritical CO2 as a solvent is also compatible with the use of subcritical water.Maintained liquid despite a temperature above 100°C by an increase in its pressure, the water thus called subcritical sees its solvent properties modified. Weakly polar compounds thus become soluble in water.

This process allows:
  • Perform extractions on undried products
  • Adjust water solubility characteristics by changing process parameters
  • Freedom from organic solvents
  • To extract phenolic compounds

For larger applications, our equipment is developed specifically for this process.
