A serial dilution is the stepwise of a in. Usually the at each step is constant, resulting in a of the in a fashion. A ten-fold serial dilution could be 1, 0.1 M, 0.01 M, 0.001 M. Serial dilutions are used to accurately create highly diluted solutions as well as solutions for resulting in with a. A tenfold dilution for each step is called a logarithmic dilution or log-dilution, a 3.16-fold (10 0.5-fold) dilution is called a half-logarithmic dilution or half-log dilution, and a 1.78-fold (10 0.25-fold) dilution is called a quarter-logarithmic dilution or quarter-log dilution. Serial dilutions are widely used in experimental sciences, including,,,.

The serial dilution technique1 using pipets is a well-established way to. Direct dilution provides a number of advantages over serial dilution. • This technique is based upon the ability of a single organism to multiply in the. What is the advantages and disadvantages to the serial dilution agar plate.

Contents • • • • • In biology and medicine [ ] In and, besides the more conventional uses described above, serial dilution may also be used to reduce the concentration of microscopic organisms or cells in a sample. As, for instance, the number and size of that grow on an plate in a given time is concentration-dependent, and since many other diagnostic techniques involve physically counting the number of micro-organisms or cells on specials printed with grids (for comparing concentrations of two organisms or cell types in the sample) or wells of a given volume (for absolute concentrations), dilution can be useful for getting more manageable results. Serial dilution is also a cheaper and simpler method for preparing than. In homeopathy [ ].
