Soxhlet distillation extraction removes liquid phases (oil and brine) from core samples by virtue of a solvent vaporization and condensation process. The cleanliness of the sample is determined from the color of the solvent once it has permeated from the samples and condensed. The samples are placed in the extractor and cleaned by refluxing solvent. The solvent in this closed system is externally heated and vaporized continuously in a flask, flow through the samples in the extraction tube, condenses at the top of the assembly. The condensate falls back into the sample chamber. When the latter is full, the dirty solvent returns to the flask via a siphoning reflux sidearm located at the base of the sample chamber. Due to the difference in boiling point temperatures, only the solvent evaporates while the oil finds itself trapped in the flask.
