Description
Phosphate buffer solution pH 3.0 is an analytical reagent buffer prepared to Reag. Ph. Eur. 4.1.3 (reference 4000500) for laboratory work at a defined acidic phosphate pH. The solution exhibits a density of roughly 1 g/cm³ and a boiling point of 100 °C, consistent with an aqueous buffer matrix. It is delivered as 1 l in a plastic container with a unit weight of about 1,300 kg, suitable for everyday analytical and quality-control use. Phosphate buffers at pH 3.0 are frequently required for sample preparation, pH adjustment and pharmacopoeial procedures that specify this acidic phosphate system. This phosphate buffer solution pH 3.0 from manufacturer Carl ROTH is positioned within the special buffer solutions range linked to European Pharmacopoeia 4.1.3 monographs. The ready-made litre pack helps laboratories avoid multi-step preparation from individual salts while maintaining a clear specification trail. Applications span analytical chemistry benches, method support and related wet-chemistry tasks, including environments that also run liquid chromatography workflows. Plastic packaging aids practical dispensing, transport within the lab and orderly placement in buffer storage areas.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Phosphate buffer solution pH 3.0, Reag. Ph. Eur. 4.1.3, 4000500, 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.
