Use the website when you need a quick C1V1 = C2V2, serial dilution, or make-solution mass — without installing an app or creating an account. Sign in to keep saved calculations synced with the Lab Laps mobile app.
This free online dilution calculator helps you prep solutions in the browser. Solve C1V1 = C2V2 for stock and solvent, plan a serial dilution series, reverse a mix you already made, or calculate solid mass for a target concentration. Sign in to the web workspace or use the app when you want saved calculations that sync across devices.
Useful for researchers, students, and lab teams who prep buffers, antibiotics, standards, or cell-culture media — anyone who needs a fast dilution or serial series without opening a spreadsheet.
Yes. The public dilution calculator is free and does not require a login. Enter concentrations and volumes to get stock and solvent amounts, run a serial dilution series, reverse a dilution, or calculate mass to make a solution.
Enter start concentration (C1), target concentration (C2), and final volume (V2). The calculator returns how much stock (V1) and solvent to mix. Units cover common molar and mass/volume concentrations used at the bench.
Yes. Choose serial dilution mode, set the starting concentration, dilution factor, number of steps, and transfer volume. The tool shows each step concentration and the volumes to pipette.
Reverse dilution finds the final concentration and volume when you already know how much stock and solvent you mixed. Make solution calculates the mass of solid needed for a target concentration and volume (with molecular weight when using molar units).
No. This public page is for quick calculations only — nothing is saved to an account. For saved calculations that sync with the Lab Laps mobile app, sign in and use /app/dilution.
Use the public page for a quick, no-login dilution. Sign in for synced saved calculations across devices at /app/dilution — or use the mobile app alongside protocols and timers.
