What are the applications of serial dilution?

In microbiology, serial dilutions are used to estimate the concentration of microorganisms, facilitating the growth of readily countable colonies. In biochemistry, serial dilution assists in achieving specific concentrations of reagents from higher stock concentrations. In homeopathy, this technique involves diluting substances in distilled water or alcohol. It is thought that dilution enhances therapeutic characteristics through an activation of the substance’s essential energy. Pharmaceutical labs utilize serial dilution to precisely achieve required chemical concentrations, as it is more efficient than doing individual dilutions.
