Soxhlet extractor - Sciencemadness Wiki

A Soxhlet extractor is a piece of laboratory apparatus commonly used in continuous extractions, in the extraction of a desired compound, often an organic compound, from a solid material. Typically, a Soxhlet extraction is used when the desired compound has relative low solubility in a solvent (which may or may not change with temperature), and the impurity is completely …

How to use a Rotary Evaporator

Apr 01, 2010 The flask with the solution is placed on the rotary evaporator. The use of a bump trap prevents the solution from accidentally splashing into the condenser (and being contaminated). It is highly advisable to start with a clean bump bulb in case something bumps over after all! This would allow the experimenter to recover the solution or solid. 3.

What are Applications of a Rotary Evaporator? - Rotovap

Dec 20, 2019 A rotary evaporator is electronically controlled so that the rotation of the flask can be kept at a constant speed, and the mixture can form a film on the inner surface of the flask, creating a larger surface for heating. All of these factors contribute to the faster evaporation speed of solvent, which means higher efficiency and better accuracy.

May 15, 2016 The problem with coconut oil, though, is that once you get the coconut oil extract, I don't know of any way to separate the KLs from the coconut oil. With alcohol/water, you can just let it evaporate (or use a rotary evaporator, if you want to be fancy). Coconut oil solidifies near room temperature, so I don't think it would work well for vaping.

Nov 20, 2020 The Soxhlet extraction method uses a number of different glassware pieces. A Soxhlet extractor is placed between a condenser and a flask. The refluxing solvent from the flask is heated and washes over the solid placed within the Soxhlet extractor. As a result, the desired low solubility compound is extracted out and siphoned into the flask.
