dilution

 [di-loo´shun]
1. reduction of concentration of an active substance by admixture of a neutral agent.
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.

di·lu·tion

(dī-lū'shŭn),
1. The act of being diluted.
2. A diluted solution or mixture.
3. In microbiologic techniques, a method for counting the number of viable cells in a suspension; a sample is diluted to the point where an aliquot, when plated, yields a countable number of separate colonies.

2. a method of obtaining a pure bacterial culture by rapid transfer of a small amount of material from one nutrient medium to a succeeding one of the same volume.
