Description
Phosphate buffer solution pH 7.0 is a ready-to-use analytical reagent conforming to Reag. Ph. Eur. 4.1.3 for precise neutral pH control in pharmaceutical testing and laboratory analysis. With a density of approximately 1 g/cm³ and a boiling point of 100 °C, the aqueous phosphate system delivers stable pH 7.0 conditions suitable for electrode calibration, titrations, and sample preparation. The product is supplied in a practical 1 l plastic bottle designed for routine bench use. Prepared to European Pharmacopoeia reagent chapter 4.1.3 under reference 4003700 from manufacturer Carl ROTH, it meets documented requirements for quality-control and method-development applications. Analytical laboratories rely on this defined phosphate buffer when reproducible neutral media are needed for assays, system suitability checks, or buffer blanks. As part of the specialised Ph. Eur. 4.1.3 pH-buffer solutions range, it offers straightforward handling and consistent performance for everyday analytical chemistry workflows without further dilution or adjustment.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Phosphate buffer solution pH 7.0, Reag. Ph. Eur. 4.1.3, 4003700, 1 l, 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.
