Supercritical Fluid Extractors

Applied Separations

spe-ed series Supercritical Fluid Extractors

The spe-ed SFE series allows the extraction of compounds from the feed material in a number of parallel extraction vessels in an oven. The spe-ed SFE series includes the spe-ed SFE NP, which is designed for the extraction of natural products such as essential oils, pigments, flavours, fragrances and medicinal compounds. The spe-ed SFE 15000 provides higher pressures to increase the solubility of compounds, such as triglycerides, which are harder to extract. The spe-ed SFE series is capable of inline trapping, modifier addition & multiple flow paths.
