Dilution Factor Formula:
| From: | To: |
The dilution factor (DF) is a dimensionless quantity that represents the ratio of the initial concentration to the final concentration of a solution after dilution. It indicates how many times a solution has been diluted.
The calculator uses the dilution factor formula:
Where:
Explanation: The formula calculates how many times more concentrated the original solution is compared to the diluted solution.
Details: Accurate dilution factor calculation is crucial for laboratory preparations, chemical dilutions, pharmaceutical formulations, and ensuring proper concentration levels in various scientific and industrial applications.
Tips: Enter both initial and final concentrations in mg/L. Both values must be positive numbers, and the initial concentration must be greater than the final concentration for a valid dilution.
Q1: What does a dilution factor of 10 mean?
A: A dilution factor of 10 means the original solution was diluted 10 times, making it 10 times less concentrated than the original.
Q2: Can dilution factor be less than 1?
A: No, dilution factor should always be greater than 1 since initial concentration must be higher than final concentration in a dilution process.
Q3: How is dilution factor related to dilution ratio?
A: Dilution factor is the inverse of the dilution ratio. For example, a 1:10 dilution has a dilution factor of 10.
Q4: What units should I use for concentration?
A: This calculator uses mg/L (mass per volume), but the formula works with any consistent concentration units (μg/mL, g/L, etc.).
Q5: When would I need to calculate dilution factor?
A: Dilution factor calculations are essential in laboratory work, pharmaceutical preparations, chemical manufacturing, and any process requiring precise concentration adjustments.
