Tools

Dilution calculator

Prepare a lower working concentration from a stock solution. Enter the stock and target concentrations and the final volume; the tool returns the volume of stock to take and the diluent to add (C₁V₁ = C₂V₂).

C₁ · V₁ = C₂ · V₂

Stock to take (V₁)
0.40 mL
Diluent to add
1.60 mL

Take V₁ of stock and bring to V₂ with diluent. Use any consistent units for C₁/C₂. For in-vitro research calculations only.

For in-vitro research use only

A standard bench-dilution calculation for preparing in-vitro working solutions. It does not advise on usage of any kind.
