What is a pH 4.01 buffer solution used for? A pH 4.01 ± 0.01 (25 °C) buffer solution, 500 ml, is used for the calibration and control of pH meters in the acidic range. It is required: For 2- or 3-point calibration (e.g. together with pH 7.00 and pH 9/10). When measuring samples in the acidic range (pH < 7). Typical applications: food analysis (e.g. juices, wine), environmental analysis (soil or water samples), industrial processes involving acidic solutions, and in laboratories. A pH meter measures most accurately in the range in which it has been calibrated – therefore, pH 4.01 is important for precise measurements in an acidic environment. What do the details on the bottle mean? pH 4.01 This is the exact target pH value of the buffer solution at the reference temperature. The chemical composition keeps this value stable. ± 0.01 This is the very narrow tolerance. The actual pH value is at most 0.01 pH units above or below 4.01 (i.e. between 4.00 and 4.02). This demonstrates the high accuracy of the solution. (25 °C) The specified pH value applies precisely at 25 °C, as the pH value is temperature-dependent. Measuring instruments take this into account via temperature compensation. 500 ml This is the volume of the solution. The solution is used for the precise calibration of a pH meter in the acidic range, whereby 4.01 at 25 °C is the exact reference value with a very small deviation of ± 0.01.
