Description
Buffer solution pH 7.0 is a ready-to-use analytical reagent conforming to Reag. Ph. Eur. 4.1.3 for reliable pH control in pharmaceutical and laboratory workflows. With a density of approximately 1 g/cm³, this aqueous preparation maintains a stable neutral value of pH 7.0 and supports consistent electrode calibration, titrations, and sample conditioning. The solution is supplied in a practical 1 l plastic bottle suited to routine bench use and instrument verification. Prepared according to European Pharmacopoeia reagent chapter 4.1.3 (reference 4003500) from manufacturer Carl ROTH, it fits quality-control and method-development environments that require documented pharmacopoeial compliance. Analytical laboratories benefit from its defined composition when establishing reproducible neutral conditions for assays, buffer blanks, or system suitability checks. As part of the specialised pH-buffer solutions range aligned with Ph. Eur. 4.1.3, the product offers straightforward handling for everyday analytical chemistry tasks without additional preparation steps.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Buffer solution pH 7.0
What is this article?
Buffer solution pH 7.0 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 Produits chimiques.
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.
Which category should I open next?
