Description

Description

pH Buffer Standard Solution for pH electrode calibration with Certificate of Analysis (DIN 19267). pH is 9,23 ±0.02 at 25°C (S11M011) from Hach.

Application: For drinking water, wastewater and process water.

Summary of method: A combination pH electrode develops a potential at the glass/liquid interface. At a constant temperature, this potential varies linearly with the pH of the solution. The pH is the hydrogen ion activity in a solution and is defined as –log10a(H+), where a (H+) is the activity of the hydrogen ion. The sample pH can change when carbon dioxide is absorbed from the atmosphere. In water that has a high conductivity, the buffer capacity is typically high and the pH does not change much.

Shelf life: 18 months.

Color coded: No.

Special remarks: Observed shelf-life after opening, following recommended storage and use: 3 months.
