Description
Phosphate buffer solution pH 7.5 0,05 M is a ready-to-use analytical buffer intended for laboratory procedures that require a mild phosphate medium at near-neutral pH. Prepared at 0,05 M and adjusted to pH 7.5, the solution is specified as Reag. Ph. Eur. 4.1.3, supporting work that follows European Pharmacopoeia buffer guidance. Typical physical characteristics include a density of about 1 g/cm³ and a boiling point of 100 °C, as expected for an aqueous buffer of this type. The product is supplied in a 1 l pack suitable for everyday analytical use, sample preparation, and method development. This special buffer solution from manufacturer Carl ROTH forms part of the Ph. Eur. 4.1.3 pH-buffer range and helps maintain defined pH conditions during titrations, reagent handling, and related assays. Laboratories can apply the 0,05 M phosphate system wherever a lower-strength buffer at pH 7.5 is preferred. The litre unit offers a convenient stock volume for repeated dispensing without the need to prepare the buffer from solid components on site, supporting consistent routine workflows.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Phosphate buffer solution pH 7.5 0,05 M, 1 l
What is this article?
Phosphate buffer solution pH 7.5 0,05 M, 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 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.
