It says that dilution ratio and factor is the same, and then it says there is confusion and gives two definitions for them, one to be a pure solvents ratio, the other a ratio of initial vs final. So then what's going to be? Are they two different things? Or they're the same thing and then the use of a pure ratio should be labeled as a mistake? |

:Yes, this article is actually about ''dilution factor'', but there is common confusion because this factor is commonly expressed as a ratio. How can we make this clearer?

== Definition of Dilution Factor == |
|||
I have found different definitions online, but my understanding is that dilution factor is the inverse of dilution; e.g. if you add 0.1 mL of broth culture to 0.9 mL of dilutent, you end up with a 1/10 or 1:10 dilution but a dilution factor of 10. Even the linked article [https://faculty.weber.edu/ewalker/Chem2990/Chem%202990%20Readings%20-%20Dilutions.pdf]says this. However, the article also says that if you go from a less concentrated to more concentrated, the dilution factor can be less than zero.

Contested deletion
[edit]This page should not be speedy deleted as an unambiguous copyright infringement, because: the external website is dated "22nd March, 2011", a date prior to which the offending content already existed in Wikipedia ([1]), therefore the website copied WP. --Fgnievinski (talk) 05:26, 24 July 2015 (UTC)

Definition of Dilution Factor
[edit]I have found different definitions online, but my understanding is that dilution factor is the inverse of dilution; e.g. if you add 0.1 mL of broth culture to 0.9 mL of dilutent, you end up with a 1/10 or 1:10 dilution but a dilution factor of 10. Even the linked article [2]says this. However, the article also says that if you go from a less concentrated to more concentrated, the dilution factor can be less than zero.
