Description
Redox Standard ROTI®Calipure 440 mV (25 °C) is a ready-to-use calibration solution for verifying redox electrodes and supporting redox titration procedures. The specified potential of 440 mV at 25 °C enables dependable instrument checks in analytical and quality-control laboratories. Packaged in a 500 ml plastic bottle, the standard is well suited to regular bench use. Reported physical properties include a density of 1,134 g/cm³ and a boiling point of 100 °C, supporting stable handling under normal laboratory conditions. Consistent redox reference materials help laboratories maintain measurement reliability when calibrating sensors or validating electrochemical methods. This solution from manufacturer Carl ROTH forms part of the ROTI®Calipure range used in professional titration applications. It serves research, industrial QA and teaching environments that need defined redox potential standards for electrode performance assessment and routine redox titration work.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Redox Standard, ROTI®Calipure 440 mV (25 °C), 500 ml, plastic
What is this article?
Redox Standard, ROTI®Calipure 440 mV (25 °C), 500 ml, plastic 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.
