Into a sterile 15 mL plastic centrifuge tube was placed 0.0021 g decapeptide, 0.0016 g sodium acetate, 0.0094 g sodium saccharin and 7.0 g sterile water. The pH was adjusted using only the necessary amount of acid saccharin to a pH of 4. Into a new 15 mL plastic centrifuge tube was placed 3.5 mL of a pH 4 solution. The pH was adjusted using only the necessary amount of 1.0N NaOH to a final pH of 7.
