![]() ![]() The assembly is supported by a clamp screwed to a vertical rod, itself fixed to the heating mantle. Flexible plastic tubing connects the condenser to the water cooling unit. The first comprises a boiling flask, soxhlet extractor and condenser. The apparatus consists of a distillation/extraction glassware unit and a heating mantle with thermostatic controller. Due to the difference in boiling point temperatures, only the solvent evaporates while the oil finds itself trapped in the flask. 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. Using Soxhlet Ethanol Extraction to Produce and Test Plant Material (Essential Oils) for Their Antimicrobial Properties CC BY-NC-SA 3.0 Authors: James Redfern Manchester Metropolitan. The condensate falls back into the sample chamber. The solvent in this closed system is externally heated and vaporized continuusly in a flask, flow through the samples in the extraction tube, condenses at the top of the assembly. The samples are placed in the extractor and cleaned by refluxing solvent. The cleanliness of the sample is determined from the color of the solvent once it has permeated from the samples and condensed. Soxhlet distillation extraction removes liquid phases (oil and brine) from core samples by virtue of a solvent vaporization and condensation process. DW-SXT-06/DW-SXT-02 Soxhlet extractor takes use of Soxhlet extraction and weight determination method to analyze fat content, that is, dissolve fat with an organic solvent, then extract fat from the solvent, dry it and weigh, finally calculate the fat content. ![]()
