ABOUT THIS TOOL

Calculate how much stock solution and diluent you need to prepare a target concentration. Supports molar concentration and volume conversions.

Important: The stock and target must refer to the same solute. This assumes additive volumes and no chemical reaction on mixing.

How it works

Method: C₁ × V₁ = C₂ × V₂. Calculate V₁ = C₂ × V₂ / C₁ after converting concentration units.

Example: To make 100 µL of a 0.5 mM solution from a 10 mM stock, use 5 µL stock and 95 µL diluent.
