Key takeaways
DilutionTools is a set of free, fast dilution calculators for the lab and beyond — from the C₁V₁ = C₂V₂ equation to serial dilutions, mixing ratios, alcohol dilution and dilution factors. Here is what is live today and where the site is going.
- Five calculators are live - dilution (C₁V₁ = C₂V₂), serial dilution, dilution ratio, alcohol dilution and dilution factor.
- Every tool shows the formula behind each result, so answers can be checked by hand.
- All tools are free, run in the browser and need no account.
What this site is
DilutionTools is a collection of small, fast calculators for one job: getting dilutions right. No accounts, no spreadsheets, no guessing which convention a protocol means — each tool states its formula and its convention next to the result.
What is live today
- Dilution calculator — solve C₁V₁ = C₂V₂ for any variable, with molar, mass-per-volume and percent units.
- Serial dilution calculator — the concentration and pipetting volumes for every step of a series.
- Dilution ratio calculator — 1:X ratios to volumes and back, with a printable chart.
- Alcohol dilution calculator — water to add for a target ABV or proof.
- Dilution factor calculator — fold-changes from volumes or concentrations.
What is next
More solution-prep tools are on the way — molarity, concentration conversions and common lab preparations — along with guides that walk through the worked examples behind each calculator. If a calculation you need is missing, tell us.
