Description
Acetate buffer solution pH 4.5 is a ready-to-use analytical reagent prepared to Reag. Ph. Eur. 4.1.3 for reliable acidic buffering in pharmaceutical testing and general laboratory workflows. Density is approximately 1 g/cm³ and the boiling point is 100 °C, giving a practical aqueous medium for titration, calibration and sample conditioning steps that call for an acetate system at pH 4.5. The product is packed as 1 l in plastic, suited to everyday bench work and extended analytical series. Quality-control and research laboratories working under European Pharmacopoeia guidance use such specialised buffers to keep hydrogen-ion activity stable during assays, electrode verification and method transfer. Offered by manufacturer Carl ROTH within the pH-buffer solutions Ph. Eur. 4.1.3 portfolio, the solution is intended for professional analytical chemistry settings. Its defined pH of 4.5 supports applications that specify acetate buffering capacity at this level. The 1 litre unit weighs 1,3 kg, which aids inventory management in chemical stores and QC departments while remaining easy to handle during routine preparation and measurement tasks.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Acetate buffer solution pH 4.5, Reag. Ph. Eur. 4.1.3, 4012500, 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.
