Description
Sodium acetate buffer solution pH 4.5, 0,5 M is a ready-to-use analytical reagent conforming to Reag. Ph. Eur. 4.1.3 for controlled buffering in pharmaceutical and laboratory applications. The 0,5 M sodium acetate system delivers a defined pH of 4.5, with a density of approximately 1 g/cm³ and a boiling point of 100 °C, supporting reproducible titration, calibration and sample-preparation work. Supplied as a 1 l unit, it fits both routine bench protocols and larger analytical series that require a standardised acetate medium. Laboratories operating under European Pharmacopoeia procedures rely on such specialised buffers to maintain consistent hydrogen-ion activity during quality-control assays, electrode checks and method development. The product from manufacturer Carl ROTH forms part of the pH-buffer solutions Ph. Eur. 4.1.3 range and is intended for professional analytical chemistry environments. Its combination of 0,5 M strength and pH 4.5 makes it suitable wherever a sodium acetate buffer at this concentration and acidity is specified. The litre pack has a weight of 1,3 kg, facilitating stock control in chemical stores and QC departments while remaining practical for daily laboratory handling.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Sodium acetate buffer solution , pH 4.5 0.5 M, Reag. Ph. Eur. 4.1.3, 4014200 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.
