A supercritical fluid extraction (SFE) apparatus is provided that is capable of being operated in a continuous and/or steady-state fashion. The SFE apparatus may include an extraction assembly. The extraction assembly may include a first extraction chamber (FEC) to contain a first amount of source material from which a compound is to be extracted, and a second extraction chamber (SEC) to contain a second amount of the source material. The extraction assembly may include a valve to control a flow of a solvent into the FEC or the SEC. The SFE apparatus may include a collection chamber that is mounted substantially perpendicular to the extraction assembly. Other embodiments are described.
