For phosphate buffers, the pH increases with decreasing temperature. Compared with a buffer at 25 °C, buffers at 4 °C will be 0,08 pH unit higher and a buffer at 37 °C will be 0,025 pH unit lower. The concentration of phosphate also influences pH. ; Typical Buffer Preparation/Formulations: 1 M Potassium Phosphate Monobasic, 1 M Potassium Phosphate Dibasic, 5 M Sodium Chloride
