High Pressure Supercritical/Subcritical Extraction
This is the most technologically advanced extraction system in the world. Research into the techniques and applications of this amazing process is ongoing and Eden Labs is at the forefront of these investigations. There are many gases and liquids that are highly efficient as extraction solvents when put under pressure and we offer multiple systems to best utilize them.
Eden Labs has been working with SFE-CO2 since 1997, continuously improving on the processes and the technology to either optimize existing products or develop completely new, high-quality solutions for a variety of end markets using our latest designs. Our combination of extensive extraction experience and advanced mechanical technology translates into shorter extraction times, wider range of use, less energy use, and...tailored solutions—optimum, cost-effective results that give our customers an edge.
The advantages of SFE are the versatility it offers in pinpointing the constituents you want to extract from a given material and the fact that your end product has virtually no solvent residues left in it (CO2 evaporates completely). Besides being the method of choice for applications designed to extract flavors and aromas, SFE-CO2 is also gaining momentum in the high-growth sector of plant substances used in nutraceuticals and food supplements. In these industries, the requirements for purity are very high and conventional methods simply are not up to the challenge. SFE-CO2 meets the toughest process standards and delivers results, including higher yields—considerations that make SFE-CO2 an alternative well worth considering.
New Hi-flo Supercritical System
Eden Labs, latest generation, just released in April 2013 is called the Hi-flo Supercritical system. It has revolutionized the Supercritical CO2 extraction application. The most amazing aspect of this new technology is it extracts 3-4 times faster than any of our competition, including our older systems. If you have an older Eden Labs system and want an upgrade, we can significantly improve your extraction times and reduce energy expenditures. Please see our Hi-flo retrofit kit in our online store.

Recirculating Supercritical CO2 Unit (Closed loop system)
The original intent of this research was to find a way to recover and re-use the gases in a way that did not require additional compressors and pressure vessels which added cost and complexity to previous generations of extractors. What we discovered was that our new design not only recovered the gases efficiently, but added stability to the process. The old method of supercritical extraction starts with a cylinder of CO2 or other gas. The gas is fed in a liquid state to a pump which pumped it through a pressure vessel packed with the material to be extracted. The extract saturated gas then de-pressurized into a separator vessel which caused the extract to fall out and the gas exited the vessel. CO2 was typically vented off.
The biggest problem with this method was the original tank of gas was de-pressurizing and cooling as the liquefied gas was being drained from it. This caused cavitation problems with the pumps and variations in temperature and pressure across the system due to the original variations in the supply cylinder. Eden Labs system is steady state. Once the parameters of temperature and pressure are set, everything remains steady. The operator can walk away from the process and tend to other duties (or relaxation knowing that in a few hours he or she can come back and find a completed extraction!) Simply close a valve and the remaining gas is pumped back to the storage vessel and the extract can be drained from the system.
