Acetate Buffer (pH 3.6 to 5.6) preparation guide and recipe. Recipe can be automatically scaled by entering desired final volume. Sodium acetate buffers are used for purification and precipitation of nucleic acids, as well as for protein crystallization and staining gels …

Prepare the exact amounts of sodium acetate (anhydrous or trihydrate) using balance and put it into the water to dissolve. A magnetic stirrer can be used to speed up the process. After the sodium acetate is dissolved, adjust the pH with acetic acid (glacial) or NaOH. Add distilled water to the final volume.

Choose a buffer based on your pH requirements as well as the pKa, a measure of acid strength that accounts for pH, concentration, and temperature. Regulatory or purity needs for your exact application should also be considered. The following tables can help you navigate preparation of many common buffer solutions by pH and pKa.
