Description
Buffer solution pH 9,22 ±0,01 (20 °C) is a ready-to-use calibration buffer from the ROTI®Calipure line for reliable pH-value determination. The stated set point of 9,22 with a tolerance of ±0,01 at 20 °C supports accurate electrode calibration and verification in alkaline working ranges. Physical data include a density of 1,001 g/cm³ and a boiling point of 100 °C, consistent with an aqueous buffer matrix. Supplied as a 500 ml pack from manufacturer Carl ROTH, the solution is intended for routine laboratory calibration of pH meters, sensors, and related measurement systems. Ready-to-use presentation reduces preparation steps and helps maintain consistent reference conditions across shifts and instruments. The alkaline buffer point is useful for quality control, analytical chemistry, and process monitoring where measurements near pH 9 must be traceable to a defined standard. The 500 ml volume suits shared bench use while remaining practical for individual workstations. Density information supports handling and documentation within pH determination workflows.
This article belongs on pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Buffer solution pH 9,22 ±0,01 (20 °C), ROTI®Calipure, ready to use, 500 ml is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in pH buffers & conductivity standards, inside Buffers & pH solutions, in Lab chemicals.
A pH buffer for calibration has a stated pH at a stated temperature, often traceable. A conductivity standard has a stated conductivity. They are not general reagents and they should not be poured back into the bottle. The temperature of the measurement has to be the temperature on the label, or the meter has to compensate.
A buffer resists a change in pH when a little acid or base is added. It does that because a weak acid and its conjugate base are both present. A pH buffer used to calibrate a meter has a stated value at a stated temperature. A biological buffer such as Tris or HEPES is chosen because it holds the pH of a living system and does not poison it. Conductivity standards are the sister articles for a conductivity meter. The ions are on PubChem. Electrode calibration practice sits with EURAMET and BELAC.
