Purpose
pH-Reference buffer solutions are intended for verification, calibration, graduation (setting, adjustment), performance testing, qualification (IQ/OQ/PQ), verification and validation of pH meters, as well as any other devices that have pH electrodes in their design.
The pH of Reference Scientific and Production Center’s buffer solutions is determined using the most accurate primary method possible—the IUPAC method using Harned cells. pH-Reference buffer solutions are certified standard samples according to ISO 17034.
These buffer solutions can be used with any pH meters that have an error of ± 0.03 pH.
Metrological characteristics of our buffer solutions:
— Buffer solutions (1,68* ± 0,01) pH;
— Buffer solutions (4,01* ± 0,01) pH;
— Buffer solutions (6,86* ± 0,01) pH;
— Buffer solutions (7,01* ± 0,01) pH;
— Buffer solutions (7,41* ± 0,01) pH;
— Buffer solutions (9,18* ± 0,01) pH;
— Buffer solutions (10,01* ± 0,01) pH;
— Buffer solutions (12,45* ± 0,01) pH.
* The nominal pH is stated at 25°C. The exact certified pH is stated in the batch certificate and may differ from the nominal value (stated above) by no more than ±0.01 pH. The exact pH value on the certificate should be used as a guide. The exact certified pH at 20°C is also stated in the certificate.
