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.

Prevents drying out and maintains the functionality of the electrode Stable electrolyte and pH buffer for precise measurement results Ideal for laboratories, industry, and research The saturated KCl solution ensures that the electrode always remains moist and measures reliably when needed. This extends the service life of the electrode and ensures the accuracy of the measurements over the long term. Practical & hygienic: The 500 ml bottle has an integrated hygienic cap that protects the solution from contamination. Simply squeeze the bottle to dispense the required amount into the upper part – clean, controlled, and user-friendly.
