The formula for dilution factor is as follows: dilution factor or DF equals Vf or final volume over Vi which is the initial volume. The final volume equals diluent plus aliquot. An aliquot is a sub-volume calculation of ... More »

When a unit volume of a liquid substance is mixed with an appropriate volume of a liquid solvent to obtain a desired concentration, it is called a simple dilution. A series dilution refers to repeating the process of a s... More »

Multiply the average number of colonies on an agar plate by the dilution factor to find the number of colony-forming units. Colony-forming units give indication of the number of culturable bacteria and fungi in an aqueou... More »
