1. What is Dilution Factor?

The dilution factor (DF) is a dimensionless quantity that represents the ratio of the final volume to the original sample volume after dilution. It indicates how many times the original sample has been diluted.

2. How Does the Calculator Work?

The calculator uses the dilution factor formula:

Where:

• \( DF \) — Dilution Factor (dimensionless)
• \( V_s \) — Sample volume (mL)
• \( V_d \) — Diluent volume (mL)

Explanation: The formula calculates the factor by which the original sample concentration is reduced after adding diluent.

3. Importance of Dilution Factor Calculation

Details: Accurate dilution factor calculation is crucial in laboratory settings for preparing samples of appropriate concentration for analysis, ensuring accurate measurements, and maintaining consistency in experimental procedures.

4. Using the Calculator

Tips: Enter sample volume and diluent volume in mL. Both values must be valid (sample volume > 0, diluent volume ≥ 0).

5. Frequently Asked Questions (FAQ)

Q1: What does a dilution factor of 1 mean?
A: A dilution factor of 1 means no dilution has occurred (V_d = 0).

Q2: How is dilution factor related to concentration?
A: The final concentration equals the original concentration divided by the dilution factor.

Q3: Can dilution factor be less than 1?
A: No, dilution factor is always ≥ 1 since it represents the ratio of final to initial volume.

Q4: What's the difference between dilution factor and dilution ratio?
A: Dilution factor is a single number (e.g., 10), while dilution ratio is typically expressed as a ratio (e.g., 1:10).

Q5: When would I need to calculate dilution factor?
A: Dilution factor calculations are essential in chemistry, biology, medical laboratories, and any field requiring precise sample preparation and concentration adjustments.
