Serial dilution - Wikipedia. A serial dilution is the stepwise dilution of a substance in solution. Usually the dilution factor at each step is constant, resulting in a geometric progression of the concentration in a logarithmic fashion. A ten- fold serial dilution could be 1 M, 0.
How to Do Serial Dilutions. A dilution in chemistry is a process that reduces the concentration of a substance in a. The first tube will be a 1:10 dilution. Serial Dilutions Return to START! A 4-fold dilution is the same thing as a 1/4 dilution. For example, if you performed a 1/2000 dilution. Estimation method for serial dilution. Ten-fold serial dilutions. Figure 26: A ten-fold dilution. Ten-fold serial dilutions.
Serial Dilution Calculations. Separate Calculations for Each Step. If there are only a few serial dilutions, the calculations can be done separately for each.
M, 0. 0. 1 M, 0. 0. M .. Serial dilutions are used to accurately create highly diluted solutions as well as solutions for experiments resulting in concentration curves with a logarithmic scale. A tenfold dilution for each step is called a logarithmic dilution or log- dilution, a 3. Serial dilutions are widely used in experimental sciences, including biochemistry, pharmacology, microbiology, and physics. In biology and medicine. As, for instance, the number and size of bacterial colonies that grow on an agar 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.
HOW TO MAKE SERIAL DILUTIONS 1. 10-fold serial dilutions.
In homeopathy, serial dilutions (called potentisation) are often taken so far that by the time the last dilution is completed, no molecules of the original substance are likely to remain. Clinical Chemistry: Principles, Procedures, Correlations. Lippincott Williams & Wilkins, 2.

This produces 1. 0ml of the dilute solution. This dilute solution.
