Beschrijving
RH 28 is a redox buffer solution buffered at pH 7 with a defined redox potential UH of 427 mV (CH). Supplied as one bottle of 250 ml, this laboratory standard is used for checking and calibrating redox (ORP) electrodes and measurement systems. The combination of pH 7 and the specified millivolt value provides a stable reference point for verifying sensor response in aqueous samples. Analytical laboratories, process control and environmental monitoring benefit from a ready-to-use redox buffer when confirming electrode function before critical measurements. The 250 ml bottle format suits repeated verification routines on the bench without frequent reordering. This redox buffer solution from manufacturer WTW - a Xylem brand (WTW®) supports quality assurance of redox probes in research, water analysis and industrial laboratories. Net weight is 0,477 kg and gross weight 0,53 kg. Apply the solution according to standard redox electrode verification procedures to obtain reliable potential readings and maintain measurement confidence across successive series of samples.
This article belongs on pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about RH 28, ORP buffer solution pH 7, UH = 427 mV (CH), 1 bottle with 250 ml.
What is this article?
RH 28, ORP buffer solution pH 7, UH = 427 mV (CH), 1 bottle with 250 ml. is the article on this page. Luminix Health distributes WTW - a Xylem brand for laboratory use. It sits in pH buffers & conductivity standards, inside Buffers & pH solutions, in Chemicaliën.
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.
