Description
Buffer solution pH 12.00 ±0.02 (20 °C) is a ready-to-use high-alkaline calibration standard from the ROTI®Calipure line for laboratory pH-value determination. It offers a defined reference at pH 12.00 with a tolerance of ±0.02 at 20 °C, suitable for electrode calibration and verification in strongly alkaline ranges. Reported physical properties include a density of 1 g/cm³ and a boiling point of 100 °C. The solution QC, analytical and teaching laboratories can employ it for instrument checks and routine high-pH monitoring. This buffer from manufacturer Carl ROTH is aligned with determination of physical properties and standardised pH workflows. The ready-to-use presentation simplifies daily calibration, limits preparation errors and supports reproducible measurements in research, industrial and environmental settings that rely on stable alkaline buffer standards.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Buffer solution pH 12.00 ±0.02 (20 °C), ROTI®Calipure ready to use, 250 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.
