About the Dilution Calculator

Solve Cโ‚Vโ‚ = Cโ‚‚Vโ‚‚ for any missing value, or work through a full serial dilution series.

What it is

The Dilution Calculator solves the standard dilution equation Cโ‚Vโ‚ = Cโ‚‚Vโ‚‚ for whichever value is unknown โ€” stock concentration, stock volume, final concentration, or final volume โ€” with automatic conversion between common concentration and volume units. A serial dilution mode produces a full step-by-step table for a dilution series defined by a starting concentration, dilution factor, and number of steps. Dilutions are performed in a lab when a stock solution is too concentrated to use directly, and need to be brought down to a working concentration accurately.

Features

Solve for any variable

Cโ‚, Vโ‚, Cโ‚‚, or Vโ‚‚ โ€” enter the other three and get the missing one.

Unit conversion

Mix concentration and volume units freely; they're converted automatically.

Serial dilution table

Full step-by-step concentration table for a dilution series.

Diluent volume

Explicitly shows how much diluent to add to reach the target.
