What is the practical value of serial dilution?

The practice value of serial dilution is done to make an accurate amount of concentration from a dense concentration of cell. In this several process and dilution process is followed.  

Explanation:

The process which is followed is taking the sample which is to be diluted of known volume. And after that the dilute or some special solvent is added to make it dilute. The volume of solvent is known.

This process is followed until we get the accurate amount of diluted solution which is to be processed. There is significant value of serial dilution for experiment for other laboratory work. For having a perfect diluted solution, a particular expert of that field is required.
