Dilution Factor Formula:
| From: | To: |
The Dilution Factor (DF) formula calculates the factor by which a solution has been diluted. It represents the ratio of the final volume to the initial volume and is a unitless quantity used in various scientific and laboratory applications.
The calculator uses the dilution factor equation:
Where:
Explanation: The dilution factor indicates how many times the original solution has been diluted. A DF of 2 means the solution has been diluted to twice its original volume.
Details: Accurate dilution factor calculation is crucial for preparing solutions of specific concentrations, performing serial dilutions, and ensuring consistency in experimental procedures across various scientific disciplines.
Tips: Enter both initial and final volumes in mL. Ensure both values are positive numbers greater than zero. The final volume should be greater than or equal to the initial volume for meaningful dilution calculations.
Q1: What does a dilution factor of 1 mean?
A: A dilution factor of 1 means no dilution has occurred - the final volume equals the initial volume.
Q2: Can the dilution factor be less than 1?
A: No, since the final volume cannot be less than the initial volume in a dilution process, the dilution factor should always be ≥1.
Q3: How is dilution factor related to concentration?
A: The final concentration equals the initial concentration divided by the dilution factor. For example, a DF of 5 means the concentration is 1/5 of the original.
Q4: What's the difference between dilution factor and dilution ratio?
A: Dilution factor is a single number (v2/v1), while dilution ratio is typically expressed as a ratio (e.g., 1:10 means 1 part sample to 9 parts diluent).
Q5: Can this calculator handle different volume units?
A: As long as both volumes use the same unit (mL, L, μL, etc.), the dilution factor remains the same since it's a unitless ratio.
