Dilution Instructions
Take 5.00 mL of stock solution (10.00 M) and add 20.00 mL of diluent to obtain 25.00 mL of 2.00 M solution.

Calculation History

10 M → 2 M Just now
5 mL stock + 20 mL diluent = 25 mL final
5 M → 1 M Today, 10:23
2 mL stock + 8 mL diluent = 10 mL final
100 mg/mL → 10 mg/mL Yesterday
1 mL stock + 9 mL diluent = 10 mL final

How to Use the Dilution Calculator: A Complete Guide

Our real-time dilution calculator is a professional tool designed for scientists, lab technicians, students, and anyone working with solutions. It implements the fundamental dilution formula C1V1 = C2V2 to help you prepare accurate solutions quickly and efficiently.

Understanding the Dilution Formula

The core principle behind dilution calculations is expressed by the equation: C1 × V1 = C2 × V2, where:

Step-by-Step Guide

  1. Enter known values: Input any three of the four variables (C1, V1, C2, V2) and our calculator will automatically compute the missing value in real-time.
  2. Select appropriate units: Use the dropdown menus to select concentration units (M, mM, µM, g/L, mg/mL, %) and volume units (mL, L, µL).
  3. Utilize advanced features: For serial dilutions, set the dilution factor and number of dilutions. For molarity calculations, enter solute mass and molar mass.
  4. Review results: Check the calculated values and dilution instructions provided in the results panel.
  5. Save or share: Use the history feature to save calculations or share results with colleagues.

Common Applications

This dilution calculator is essential for:

Tips for Accurate Calculations

1. Always double-check your units to ensure consistency throughout the calculation.
2. Use the auto-calculate feature for real-time updates as you modify values.
3. Save frequent calculations to history for quick reference.
4. For molarity calculations, ensure accurate molar mass values for precise results.
5. When preparing solutions, always add the solute to the diluent (not vice versa) for better mixing.

Our tool simplifies complex dilution calculations, saving you time and reducing errors in solution preparation. Whether you're working with simple dilutions or complex serial dilution series, this calculator provides accurate, real-time results with professional-grade precision.
