How to Use the Dilution Calculator

This step-by-step guide will help you navigate the use of the Dilution Calculator to determine the volumes of stock solution and diluent needed to achieve your target concentration and volume.

Step 1: Enter the Stock Solution Details

  1. Stock Solution Concentration: Enter the concentration of your stock solution as a numerical value. Ensure this value is a positive number not less than 0.0001. The input accepts a step of 0.0001 for precision.
  2. Stock Concentration Unit: Choose the appropriate unit for your stock solution concentration from the dropdown menu. Available options include:

    • Molar (M)
    • Millimolar (mM)
    • Micromolar (µM)
    • mg/mL
    • µg/mL
    • Percentage (%)

Step 2: Define Your Target Concentration

  1. Desired Final Concentration: Input your target concentration. Similar to the stock concentration, this value must be a positive number equal to or greater than 0.0001.
  2. Target Concentration Unit: Select the unit corresponding to your desired final concentration. The options mirror those available for the stock concentration.

Step 3: Specify the Final Volume Required

  1. Final Volume Required: Enter the final volume of the diluted solution you want to prepare. The minimum allowable value is 0.001, with input precision up to 0.001.
  2. Volume Unit: Choose the unit for your final volume. The available units are:

    • Liters (L)
    • Milliliters (mL)
    • Microliters (µL)

Step 4: Calculate and Interpret the Results

Once you have entered all the necessary information, the calculator will automatically compute the following:

  • Volume of Stock Solution Needed: This is the amount of stock solution required to achieve your target concentration in the specified final volume. The result will be presented in milliliters (mL) with three decimal places.
  • Volume of Diluent (Solvent) to Add: This represents the amount of solvent you need to add to the stock solution to reach your final volume. It is also displayed in milliliters (mL) with three decimal places.
  • Dilution Factor: This factor reflects the ratio of the stock concentration to the target concentration, displayed as a simple factor: 1:x, with two decimal precision.

By following these steps, you can accurately determine the necessary volumes and ratios needed for your dilution task.
