Buffer Calculator

This buffer calculator provides an easy-to-use tool to calculate buffer molarity and prepare buffer solutions using the formula weight of the reagent as well as your desired volume (L, mL, or µL) and concentration (M, mM, or nM).

To calculate the amount of buffer needed, please select the desired buffer from the selection menu. The empirical formula, pKa, buffer pH range, formula weight, and product list will appear. Enter the desired final volume and desired concentration and click “Calculate Mass.”

The exact mass of the buffer will then be calculated in grams, and a step-by-step buffer recipe is automatically provided to assist in the buffer preparation process.
