Product information "Neomeris pH buffer solution pH 9.21"
The Neomeris pH buffer solution, with a pH value of 9.21, is used to calibrate pH meters. Its convenient dosing system and innovative hygienic 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 meters in the alkaline range. It is ideal for use in laboratories, industry, environmental analysis, research and education, where precise pH values are crucial.
Product benefits at a glance:
- Precise calibration: With an accuracy of ±0.02 pH at 25 °C, the solution meets the highest standards of measurement precision.
- Colour coding: The blue colour clearly indicates a pH value of 9.21 and prevents mix-ups in everyday work.
- Innovative hygienic cap: The special bottle cap reliably protects the solution from contamination and enables clean, direct dosing.
- Practical application: Squeezing the bottle dispenses the required amount of solution into the upper section – ideal for calibration without additional accessories.
- 500 ml capacity: Ideal for regular use and professional applications.
What is a pH buffer solution used for?
A 500 ml pH buffer solution with a pH of 9.21 ± 0.02 (25 °C) is used for calibrating and checking pH meters in the slightly alkaline range.
Application: For calibrating a pH meter when samples in the pH 9 range are to be measured later. For 2- or 3-point calibrations (e.g. together with pH 7.00 and, if necessary, pH 4.01 or 10.01).
Areas of application: Drinking water and wastewater analysis, environmental analysis, aquatics, as well as industrial and laboratory processes involving slightly basic solutions
A meter measures most accurately in the range in which it has been 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 is kept 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 precisely at 25 °C.
As the pH value is temperature-dependent, it changes slightly at different temperatures.
Modern pH meters therefore use temperature compensation.
500 ml
This is the volume of solution in the bottle.
The Neomeris pH buffer solution pH 9.21 is used to calibrate a pH meter accurately and in accordance with standards 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.
