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.
The original Babcock test was not suitable for estimating the fat contents of ice cream, since the sugar and other ingredients would be charred by the sulfuric acid and contaminate the fat layer. After thousands of experiments, a modified test, suitable for the purpose, was developed in 1930 by L. K. Crowe at the University of Nebraska .
The Soxhlet extractor was invented by Franz Soxhlet in 1879 for the lipid extraction from milk powder [9] and is one of the most common semi-continuous methods for lipid extraction from solid food samples. The sample is dried, ground to a fine powder and placed on a porous thimble inside the extraction chamber.
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.
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 ...

Babcock bottles for measuring the fat contents in cream have wider necks to allow for readings of 50% or more (rather than up to 8%). [12] Louis Nafis patented in 1921 a modified Babcock bottle, claimed to be less susceptible to accidental breakage. Instead of the integral long graduated neck, it had a short neck to which a rubber ring was fitted.
