How Do You Do Serial Dilutions In A Science Laboratory?
Serial dilutions are very important in biology science laboratories. It is a fundamental laboratory principle and technique that everyone needs to know when working in the laboratory. This article talks about what serial dilutions are and how to do them correctly and effectively. Let’s first look at the concept of serial dilutions. In a biology laboratory (especially microbiology), analysts are interested in finding out the quantity of bacteria in their sample. In order to do that, serial dilution is the best approach for this purpose. The reason being many times a sample contains lots of microorganism that it must be diluted in order to get an accurate count. Serial dilution is a set of dilutions with several steps in which each step has the same dilution factor. Most of the time, the dilution factor is 10. So that each time, the sample get 10 times less diluted as the previous one. In order to do it effectively in the laboratory, first set out a series of tubes with 9mL of buffer wat
