Supercritical Fluid Extraction (SFE)

  • :

Supercritical fluid extraction (SFE) is the process of separating one component (the extractant) from another (the matrix) using supercritical fluids as the extracting solvent. Extraction is usually from a solid matrix, but can also be from liquids.

SFE can be used as a sample preparation step for analytical purposes, or on a larger scale to either strip unwanted material from a product or collect a desired product. These essential oils can include limonene and other straight solvents.

Carbon dioxide (CO2) is the most used supercritical fluid, sometimes modified by co-solvents such as ethanol or methanol. Extraction conditions for supercritical carbon dioxide are above the critical temperature of 31 °C and critical pressure of 74 bar.

Addition of modifiers may slightly alter this. The discussion below will mainly refer to extraction with CO2, except where specified.

Available models:

SFE Prime:  This model is suitable for research or low output application, having vessel size 5 ml-100 ml. Best model with low recurring cost for new product identification.

SFE 2 /SFE 4: These model are suitable for research as well as small scale production for specific products /application, having vessel size 5 ml-500 ml.  SFE 2 having features of 2 sample processing while SFE 4 is suitable for 4 samples simultaneously.

SFE Helix: This model is suitable for high research, nano particle formation or high output application, having vessel size 100 ml-5000 ml.

Pilot scale/ Industrial models available on request only.
