Serial Dilution Equation:
| From: | To: |
The serial dilution equation calculates the final concentration of a solution after a series of dilution steps. It's commonly used in laboratory settings to prepare solutions of specific concentrations from stock solutions.
The calculator uses the serial dilution equation:
Where:
Explanation: The equation calculates the final concentration by dividing the initial concentration by the total dilution factor accumulated through multiple dilution steps.
Details: Accurate serial dilution calculations are essential for preparing precise concentrations in laboratory experiments, medical testing, pharmaceutical preparations, and various scientific applications where specific solution strengths are required.
Tips: Enter the initial concentration in appropriate units, enter the total dilution factor (must be greater than 1 for dilution). Both values must be positive numbers.
Q1: What units should I use for concentration?
A: The calculator works with any concentration units (mg/mL, M, %, etc.) as long as you maintain consistency between initial and final concentration units.
Q2: How do I calculate the total dilution factor for multiple dilutions?
A: Multiply individual dilution factors together. For example, three 1:10 dilutions give a total dilution factor of 10 × 10 × 10 = 1000.
Q3: Can this calculator handle very small dilution factors?
A: Yes, but extremely small dilution factors may indicate concentration rather than dilution, which may not be physically meaningful in most contexts.
Q4: What if my dilution factor is less than 1?
A: A dilution factor less than 1 would indicate concentration rather than dilution, which is not typical for serial dilution calculations.
Q5: Are there limitations to this equation?
A: This equation assumes perfect mixing and no chemical interactions that might affect concentration beyond simple dilution.
