Potassium Phosphate Buffer Preparation and Recipe Potassium phosphate buffers, sometimes called Gomori buffers, consist of a mixture of monobasic dihydrogen phosphate and dibasic monohydrogen phosphate. Sterilize by autoclaving and store at room temperature. 4): Change the value in the textbox above to scale the recipe volume. Potassium phosphate dibasic trihydrate is a key component of potassium phosphate buffer, phosphate-buffered saline (PBS), and phosphate-buffered EDTA (PBE). 1 M potassium phosphate buffer at 25 °C using various proportions of potassium phosphate monobasic and potassium phosphate dibasic has been published. This buffer is a cornerstone in various biological and biochemical applications due to its buffering capacity near physiological pH. Most neutral potassium phosphate buffer solutions consist of mixtures of the monobasic and dibasic forms to varying degrees, depending on the desired pH. Add distilled water until the volume is 1 L. pastoris.
