Preparation of sodium phosphate buffer solution

  1. Jul 23, 2012 #1
    hi guys,

    How can I prepare 20 mM sodium phosphate buffer (pH 6.9) containing 10 mM NaCl ? I mean how many grams of sodium dihydrogenphosphate, disodium hydrogenphosphate and sodium chloride are needed for 1 L of buffer solution. The buffer solution is prepared at room temperature (25C) and use at 37C.

    Thank you :smile:
