2. a substance that has undergone such a process.
serial dilution a set of dilutions in a mathematical sequence. In microbiological technique, serial dilutions are used to obtain a culture plate that yields a countable number of separate colonies. From this, a calculation of viable cells in the original suspension can be made, as a colony picked for pure culture.
