Phosphate buffer solution pH 2.8 is a ready-to-use analytical reagent prepared according to Reag. Ph. Eur. 4.1.3 under reference 4010600. This specialised phosphate buffer provides a defined acidic medium at pH 2.8 for pharmaceutical and analytical laboratory applications that follow European Pharmacopoeia requirements. The aqueous solution shows a density of approximately 1 g/cm³ and a boiling point of 100 °C. It is supplied as a 1 l fill in a practical plastic bottle, with a pack weight of 1,300 kg suitable for regular bench use. Quality-control laboratories, method-development teams and routine testing facilities rely on standardised Ph. Eur. buffers to secure reproducible results in assays, sample preparation and related procedures. Positioned in the special pH-buffer solutions Ph. Eur. 4.1.3 category, the product is offered from manufacturer Carl ROTH for professional analytical chemistry workflows. Using a pharmacopoeia-grade phosphate buffer limits preparation variability and supports compliance when monographs call for phosphate buffer solution pH 2.8. It is well suited to pharmaceutical analysis, research and industrial QC environments that demand adherence to Ph. Eur. reagent specifications.

This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?

Phosphate buffer solution pH 2.8, Reag. Ph. Eur. 4.1.3, 4010600, 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.
