Unlike alternative extraction techniques, Supercritical Fluid Extraction (SFE) provides pure, solvent-free extracts by utilizing carbon dioxide. SFE is a green alternative to solvent-based extraction techniques. The properties of a supercritical fluid can be altered by varying the pressure and temperature, allowing selective extraction. The low viscosity of supercritical carbon dioxide allows it to penetrate into the material more easily while its diffusivity allows for faster extractions. CO₂ is an environmentally friendly solvent that leaves no residue.

Enhance pressure capability

• Extraction at higher pressures (up to 8,700 psi) enables improved solubility, providing a more complete extraction in less time
• By manipulating pressure, you can selectively extract the desired material more quickly

Fractionation of your extracts

• The only SFE system on the market to incorporate three collection vessels with independent pressure control, providing the ability to selectively isolate groups of components (e.g., separate waxes , oils, and lighter materials)
• As pressure is reduced, CO₂ becomes a weaker solvent, impacting the solubility of various components

Enhanced selectivity with optional co-solvent pump

• Optional co-solvent pump enables extraction of a wider polarity range of compounds, including acids, by metering in a small proportion of organic solvent (e.g., ethanol)

Capacity to fit your productivity needs

• Choose between 5 L or 10 L extraction vessels, which hold up to 4 lbs (1.8 kg) or 8 lbs (3.6 kg) of ground material, respectively
• Self-sealing, tool-free vessel caps for enhance ease-of-use and assembly

Consistent extractions, from run-to-run

• A computer-controlled automated back pressure regulator maintains the extraction at the desired pressure

Enhanced user experience

• Automates the extraction process through an easy-to-use computer controlled interface
• Program and store specific methods for individual strains or end products

Reduced CO₂ usage

• Optional CO₂ recycler enables you to reuse CO₂ for a convenient and even greener process

As the botanical industry rapidly expands, it's important to stay competitive, especially when it comes to extracting bioactive compounds from crops. If you're using liquid carbon dioxide for cleaner, more efficient extractions, you're already on your way. Some may think the next step is to get the biggest extraction equipment to meet increasing demand. Well, not quite. With Waters you can extract the same amount of material as those bigger systems in a fraction of the time.  Learn how using the latest extraction technologies from Waters can consistently deliver the highest yield and quality from your botanical extracts.
