Description
Phosphate buffer solution pH 3.0 is a 0,1 M analytical buffer conforming to Reag. Ph. Eur. 4.1.3, intended for pharmaceutical and laboratory work that demands controlled acidic pH. Density is approximately 1 g/cm³ and the boiling point is 100 °C, supporting stable handling in aqueous analytical systems. The 1 l pack is convenient for titrations, sample dilution, mobile-phase adjustment and other procedures that specify phosphate buffer at pH 3.0 under European Pharmacopoeia guidance. Prepared by manufacturer Carl ROTH to the Ph. Eur. 4.1.3 requirement, this ready-to-use solution helps laboratories keep methods aligned with monographs and internal SOPs. The defined molarity and pH favour reproducible buffering when dissolving solids, stabilising reaction media or preparing calibration and test solutions. It is well suited to quality-control and research environments that rely on consistent phosphate buffering at pH 3.0 for dependable analytical outcomes across successive batches.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Phosphate buffer solution pH 3.0, 0.1 M, Reag. Ph. Eur. 4.1.3, 4011500, 1 l 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.
