Definition for Dilution factor

Diluent

Dimorphic

Ratio of final volume/aliquot volume (final volume = aliquot + Diluent).

To calculate a dilution factor:

Remember that the dilution factor is the final volume/aliquot volume.

EXAMPLE: What is the dilution factor if you add 0.1 mL aliquot of a specimen to 9.9 mL of diluent?

1. The final volume is equal the the aliquot volume plus the diluent volume: 0.1 mL + 9.9 mL = 10 mL
2. The dilution factor is equal to the final volume divided by the aliquot volume: 10 mL/0.1 mL = 1:100 dilution (10²)

The Concentration Factor for this problem = aliquot volume/final volume = 0.1/(0.1 + 9.9) = 0.01 or 10^-2 concentration
