Microbiologics Dilutions Guide
In microbiology serial dilutions (log dilutions) are used to decrease a bacterial Example: 1:10 dilution - if the concentration is 1000 CFU a one log |
What is a 1 2 dilution series?
A 1 in 2 dilution means 1 part solute in 2 parts solution (a part can be volume ie; mL or mass ie; g). 1 mL solute + 1 mL of water = 2 mL solution at a dilution of 1 in 2.
This means that the solute makes up 50% of the solution.How do you make a log dilution series?
A log dilution is a tenfold dilution, meaning the concentration is decreased by a multiple of ten.
To complete a tenfold dilution, the ratio must be 1:10.
The 1 represents the amount of sample added.
The 10 represents the total size of the final sample.A two-fold dilution reduces the concentration of a solution by a factor of two that is reduces the original concentration by one half.
A series of two-fold dilutions is described as two-fold serial dilutions.
