Supercritical Fluid Extraction (SFE)

Supercritical fluid extraction is an ec0-friendly, safe, clean alternative to organic solvent-based traditional extraction methods. Applying appropriate temperature, and pressure CO₂ migrates into the supercritical phase in which it can behave as a gas and liquid and act as an efficient solvent. Moreover, CO₂ preserves the chemical composition of extracts especially in heat-sensitive materials, and reduce the formation of artifacts and solvent residues. The process of CO₂ extraction is scalable from a few grams in lab-based machines up to tons in industrial scales.

Applications:

SFE has many applications both in research and industry, can be represented by but not limited to the following examples:

• Extraction of natural products, flavors, fragrances…..etc
• Vegetable and volatile oils extraction
• EPA and DHA (omega 3) industries
• Selective extraction of some non-polar active principles from plants.

Sample requirements:

• Sample size up to 250 gm (powder)
• The following pressure and temperature limits are available as default:

Max.temp: 60oC

Max.pressure: 350 bar

N.B. Please provide your applicable method within permitted max ranges of temp. and pressure, otherwise the default method will be used.
