What is SFE?

Super Critical Fluid Extraction (SFE), is an extraction process using a supercritical fluid as a solvent. When a fluid is taken above its critical temperature (Tc) and critical pressure (Pc), it exists in a condition called “the super critical fluid state”. The physical properties of the fluid in this state vary between those of a typical gas and a liquid. Variations in pressure to the fluid can alter the density of the gas, resulting in the super critical fluid having a density ranging between those of a gas and a liquid. By manipulating the pressure and temperature this method of processing can selectively extract the pure material of interest.

Why SFE?

Unlike more traditional methods of extraction SFE uses no additional solvents in the process, which translates to substantial cost savings due to a reduction in post-processing steps, clean-up, and safety and assurance measurements. More importantly the resulting natural extraction is of the purest quality possible with no residual contamination from other chemicals.
