A Soxhlet extractor is a piece of laboratory apparatus [1] invented in 1879 by Franz von Soxhlet. [2] It was originally designed for the extraction of a lipid from a solid material. Typically, Soxhlet extraction is used when the desired compound has a limited solubility in a solvent , and the impurity is insoluble in that solvent.
Soxhlet extractor. Extraction in chemistry is a separation process consisting of the separation of a substance from a matrix. The distribution of a solute between two phases is an equilibrium condition described by partition theory. This is based on exactly how the analyte moves from the initial solvent into the extracting solvent.
Accelerated solvent extraction (ASE), also known as pressurized solvent extraction (PSE), is a method for extracting various chemicals from a complex solid or semisolid sample matrix. The process uses high temperature and pressure, which results in the extraction taking less time and requiring less solvent, and possibly also giving better ...
Norovirus, sometimes called the “winter vomiting disease” or “two-bucket disease” — because it causes both vomiting and diarrhea — is on the rise across the nation, even as seasonal ...
The schools also hold their “prisoner exchange.” Students from West Point and the Naval Academy who are attending classes at their rival institution in order to begin training in joint command ...
Soxhlet is also known as the first scientist who fractionated the milk proteins in casein, albumin, globulin and lactoprotein. Furthermore, he described for the first time the sugar present in milk, lactose. The Soxhlet solution is an alternative to Fehling's solution for preparation of a comparable cupric/tartrate reagent to test for reducing ...
If you have had trouble saving for retirement, putting money away for a down payment, creating a budget, saving for family vacation or other money goals, don't feel too bad, said Brad Klontz, a...
A rotary evaporator [1] (rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.When referenced in the chemistry research literature, description of the use of this technique and equipment may include the phrase "rotary evaporator", though use is often rather signaled by other language (e.g., "the sample was evaporated ...
