Extraction & Separation Equipment

Supercritical Fluid Extraction (SFE)

Supercritical Fluid Extraction equipment includes laboratory, pilot scale and production project SFE equipment with CO2 extraction pressures to 700 bar. Features include quick opening-closing vessels, accurate mass flow controlllers, continuous process separations with liquid raw materials, fractionated separations with fluid cyclones and multi extraction vessel 'carousels'

Subcritical Water Extraction (SWE)

Subcritical Water Extraction (SWE) performs extractions at temperatures and pressures below the critical point of water (221 bar and 374 deg C). When the temperature and pressure of subcritical water increases there is a shift from the polar to the ionic state for SWE molecules. At the same time it becomes less viscous and has greater diffusivity and penetration within matrices.

Subcritical water is a powerful extraction agent for bioactive material as well as a catalyst for hydrothermal activities. For selective extraction, where temperature and pressure can be adjusted, the temperature has a greater effect. By increasing temperature, the Hydronium ion becomes more active and subcritical extractions shift from the polar to the ionic preferences.

Supercritical Fluid Chromatography (SFC)

Supercritical Fluid Chromatography offers a fast separation technique compared to HPLC with high resolution and purity of analyte peaks. 

Micronization / Homogenisation

High pressure micronization is used to create very fine & uniform powders with well defined geometries of solid particles by expansion of a HP fluid. The technique used can be either Rapid Expansion of supercritical Solutions (RESS) or Gas Anti Solvent recrystallization (GAS).

HP Sterilisation

HP sterilization at up to 10,000 bar can make any organisms inactive without thermal alteration of the product.

Phase Equilibria

Phase Equilibria system for fast determination of solubility data and high pressure observation of phase behaviour.
