Product information "Neomeris pH buffer solution pH 9.21"
The Neomeris pH buffer solution with a pH value of 9.21 is used for the calibration of pH measuring devices. The practical dosing system and the innovative hygiene cap make calibration quick and easy.
Neomeris pH Buffer Solution pH 9.21 ± 0.02 (25 °C), 500 ml – Precise Calibration in the Alkaline Range
The Neomeris pH buffer solution pH 9.21 ± 0.02 at 25 °C is a ready-to-use calibration solution for the reliable adjustment of pH measuring devices in the alkaline range. It is ideal for use in laboratories, industry, environmental analysis, research and education, where precise pH values are essential.
Product Benefits at a Glance:
- Precise calibration: With an accuracy of ±0.02 pH at 25 °C, the solution meets the highest requirements for measurement precision.
- Color coding: The blue coloration clearly identifies the pH value 9.21 and prevents mix-ups in everyday work.
- Innovative hygiene cap: The special bottle cap reliably protects the solution from contamination and allows clean, direct dosing.
- Practical application: By squeezing the bottle, the required amount of solution is transferred into the upper part – ideal for calibration without additional equipment.
- 500 ml volume: Ideal for regular applications and professional use.
What is a pH buffer solution used for?
A pH buffer solution pH 9.21 ± 0.02 (25 °C), 500 ml is used for the calibration and verification of pH measuring devices in the slightly alkaline range.
Application: For calibrating a pH meter when samples around pH 9 will be measured later. For 2- or 3-point calibrations (e.g. together with pH 7.00 and optionally pH 4.01 or 10.01).
Areas of application: Drinking water and wastewater analysis, environmental analysis, aquatics, as well as industrial and laboratory processes with slightly basic solutions. A measuring device measures most accurately in the range in which it was calibrated – therefore pH 9.21 is suitable for samples with pH values around 8–10.
What do the specifications on the bottle mean?
- pH 9.21: This is the exact target pH value of the buffer solution. The chemical composition ensures that this value remains stable.
- ± 0.02: This is the tolerance or accuracy. The actual pH value is at most 0.02 pH units above or below 9.21 (i.e. between 9.19 and 9.23).
- (25 °C): The specified pH value applies exactly at 25 °C. As the pH value depends on temperature, it changes slightly at other temperatures. Modern pH meters therefore use temperature compensation.
- 500 ml: This is the filling volume of the solution in the bottle. The Neomeris pH buffer solution pH 9.21 is used to precisely and standard-compliantly calibrate a pH measuring device in the slightly alkaline range.
Frequently asked questions
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.
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.
The shelf life is printed on the product label. Upon delivery, the shelf life is at least 7 months.
No, because the function and quality can no longer be guaranteed after the best-before date has expired.
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.
