Frequently Asked Questions
What is the C1V1=C2V2 formula?
C1V1=C2V2 is the dilution equation where C1 is initial concentration, V1 is volume of stock solution needed, C2 is final concentration, and V2 is final volume. This formula is based on the principle that the amount of solute remains constant during dilution.
How do I calculate cell dilution for experiments?
Enter your stock concentration (C1), desired final concentration (C2), and final volume needed (V2). The calculator will determine how much stock solution (V1) you need to achieve the desired dilution.
What is a dilution factor and how is it calculated?
The dilution factor is the ratio of initial concentration to final concentration (C1/C2). For example, diluting from 10 mg/ml to 1 mg/ml gives a dilution factor of 10×, meaning the solution is diluted 10-fold.
Can I use this calculator for different concentration units?
Yes, this calculator supports various units including mg/ml, µg/ml, molar concentrations (mM, µM, nM), and cell concentrations. Just ensure both C1 and C2 use the same units for accurate calculations.
How much diluent (buffer/media) do I need to add?
The diluent volume equals the final volume minus the stock volume (V2 - V1). This calculator automatically shows you how much diluent to add to achieve your target dilution.
What if I know the volume of stock I want to use instead?
If you know V1 (stock volume), leave that field filled and the calculator will determine what final concentration you'll achieve with your desired final volume.
Why is accurate dilution important in cell culture?
Accurate dilution ensures proper cell density for experiments, maintains cell viability, and provides reproducible results. Incorrect dilutions can lead to experimental failure or unreliable data.
