What is a pH buffer solution used for? A 500 ml pH buffer solution with a pH of 10.01 ± 0.02 (25 °C) is used for the calibration and performance check of pH meters – particularly in the alkaline (basic) measurement range. Usage: For example, for 3-point calibration (e.g. pH 4.01 / 7.00 / 10.01). For measurements in basic solutions (e.g. cleaning chemicals, wastewater, aquariums, industrial processes). For quality control and ensuring accurate pH values. Devices measure particularly accurately in the range in which they have been calibrated – hence pH 10.01 is important for high pH values. What do the details on the bottle mean? pH 10.01 This is the exact target pH value of the buffer solution. The solution is chemically adjusted to maintain a stable pH value of 10.01. ± 0.02 This is the accuracy/tolerance.

Neomeris pH Buffer Solution pH 10.01 – Alkaline Calibration Solution Reliable reference solution for pH calibration The Neomeris pH buffer solution pH 10.01 is a ready-to-use calibration solution for pH electrodes in the alkaline measurement range. With a reference value of pH 10.01 ± 0.02 at 25 °C, it enables reliable calibration of pH meters wherever high pH values require precise measurement accuracy. Safe usage and versatile applications The clear yellow color coding ensures easy identification of the pH value and prevents mix-ups during daily work. The hygienic cap protects the solution from contamination and allows clean and efficient handling. Why are alkaline reference solutions necessary for precise pH calibration? Alkaline calibration solutions are required to reliably set pH meters and electrodes in the high pH range. Calibration in only the acidic or neutral range is not sufficient when measurements are performed at alkaline pH values. The pH value does not change linearly across the measurement range. Particularly in the alkaline range, pH electrodes are more sensitive to deviations, aging, or contamination. An alkaline calibration solution (e.g., pH 10.01) ensures that the meter measures accurately exactly where it will be used. Where can the buffer solution be used? The pH buffer solution is versatile and suitable for: Laboratory analysis Environmental and water analysis Food monitoring Research & education Industrial processes Frequently asked questions Where can I find the safety data sheet for the solution I want to use?

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.

What is a pH 7.00 buffer solution used for? A 500 ml pH 7.00 ± 0.01 (25 °C) buffer solution is used for the calibration and verification of pH meters in the neutral range. pH 7.00 is the most important reference point because it represents the neutral point on the pH scale. It is required: For single-point calibration when measuring values close to pH 7. As the midpoint in a 2- or 3-point calibration (e.g. with pH 4.01 and 9/10). Suitable for applications such as: drinking water analysis, environmental analysis, the food and pharmaceutical industries, as well as schools, training and laboratories. As many samples fall within the pH 6–8 range, this buffer solution is particularly frequently used. What do the details on the bottle mean? pH 7.00 This is the exact target pH value of the solution at the reference temperature. The chemical composition ensures a stable neutral value. ± 0.01 This is the very low tolerance. The actual pH value is a maximum of 0.01 pH units above or below 7.00 (i.e. between 6.99 and 7.01). This demonstrates the high accuracy of the solution. (25 °C) The pH value given is accurate at exactly 25 °C, as the pH value depends on temperature. Modern pH meters take this into account via temperature compensation. 500 ml This is the volume of the buffer solution. The solution is used to precisely calibrate a pH meter in the neutral range, whereby 7.00 at 25 °C is the exact reference value with a very small deviation of ± 0.01.

Frequently asked questions Where can I find the safety data sheet for the solution I want to use? The safety data sheet is included in printed form with the delivery of the goods. The safety data sheet can be viewed or downloaded at any time in the download area of the online shop. What bottle sizes are available? Generally, there are 60/70 ml, 250 ml, 500 ml and 1,000 ml bottles. There is one exception, for example, with brands such as Hanna, where bags are sold instead of bottles. How long do the solutions last? The shelf life is printed on the product label. Upon delivery, the shelf life is at least 7 months. Can the solutions still be used after the expiry date? No, because the function and quality can no longer be guaranteed after the best-before date has expired. How can I dispose of the solutions? Please refer to the safety data sheet for more detailed information on the disposal of the solutions. Disposal must be carried out in accordance with official regulations. What is the emergency number for acute poisoning? The emergency number for the North Poison Information Centre is +49 551-19240 and is available 24/7.
