Supercritical Fluid Extractor

Supercritical fluids (SCFs) are very useful as solvents. Despite their very low density, compounds are quite soluble in SCFs. The other major advantage is that unlike with traditional solvents (benzene, hexane, etc.), the SCF has little or no environmental impact. An example of this is the extraction of caffeine from coffee using supercritical CO2.
