WebSerial dilutions are made by making the same dilution step over and over, using the previous dilution as the input to the next dilution in each step. Since the dilution-fold is the same in each step, the dilutions are a geometric series (constant ratio between any adjacent dilutions). For example: 1/3, 1/9, 1/27, 1/81. WebSerial dilution is a systematic reduction of a known or unknown entity (a solute, organism, etc.) through successive re-suspension of an initial solution (solution 0) into fixed volumes of a liquid diluent (blanks). These blanks usually consist of 0.45% saline, though the composition can be varied (7). WebA serial dilution is a series of dilutions used to reduce a dense cell culture to a more acceptable concentration. Each dilution lowers the bacterium concentration by a certain amount.
