Volusol?s DC Solution is an innovative solution composed by a mixture of ethanol, isopropanol, and a long chain hydrocarbon. Under the influence of microwaves this solution becomes highly effective in the extraction of water and lipids from biological tissue. This solution is capable of dehydrating and clearing in a single step. In general for an optimal extraction, the polarity of the solvent should be similar to that of impurity you want to remove. In histoprocessing, such impurities are generally water and lipids. The isopropanol, a polar molecule, contributes to dehydration and also improves the extraction of non-polar fatty. Ethanol, also a polar molecule, primarily serves to dehydrate. The action of both alcohols will be highly efficient under the stimulation of microwaves. The third component, an organic solvent, is chemically inert, and not polar.
