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.
However, much like the Soxhlet extraction technique, this method also is very time-consuming. [48] Solid-phase template As described above, one benefit of immobilising the template molecule on a solid support such as glass beads is the easy removal of the MIPs from the template. Following a cold wash to remove unreacted monomers and low ...

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 ...
Cell spreaders. In microbiology, a cell spreader or plate spreader is a tool used to smoothly spread cells and bacteria on a culture plate, such as a petri dish.. Cell spreaders can be made from glass, plastic, or metal, and come in various shapes.
First, individual DNA sequences are amplified by PCR from different templates and flanked with the required complementary overhangs. Second, the formerly obtained PCR products are combined together into the overlap extension PCR reaction, where the complementary overhangs bind pair-wise allowing the polymerase to extend the DNA strand.
The DNA template labeled at the 3' or 5' end, depending on the location of the binding site(s). Labels that can be used are: radioactivity and fluorescence.Radioactivity has been traditionally used to label DNA fragments for footprinting analysis, as the method was originally developed from the Maxam-Gilbert chemical sequencing technique.
