The Tocris dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.
The dilution calculator equation
The Tocris dilution calculator is based on the following equation:
Concentration(start) x Volume(start) = Concentration(final) x Volume(final)
This equation is commonly abbreviated as: C1V1 = C2V2
An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
- Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
- Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
- Enter 20 into the Volume (final) box and select the correct unit (milliliter)
- Press calculate
- The answer of 100 microliter (0.1 ml) appears in the Volume (start) box
