Description
Phosphate buffer solution pH 5.5 is a ready-to-use analytical reagent conforming to Reag. Ph. Eur. 4.1.3 for precise pH control in pharmaceutical testing and general laboratory analysis. Phosphate-based systems are widely applied where a well-defined ionic environment at pH 5.5 is required for sample preparation, chromatographic work, titrations or instrument calibration. The solution has a density of approximately 1 g/cm³ and a boiling point of 100 °C. It is supplied in a 1 l plastic bottle that suits everyday bench use and quality-control routines. As a special pH-buffer solution aligned with European Pharmacopoeia chapter 4.1.3, it offers laboratories a convenient, standardised medium without the need for in-house preparation. This buffer from manufacturer Carl ROTH supports reproducible analytical performance wherever a pharmacopoeia-grade phosphate buffer at pH 5.5 is specified. Clear pack presentation and stable physical properties facilitate reliable handling in regulated and research environments alike.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Phosphate buffer solution pH 5.5, Reag. Ph. Eur. 4.1.3, 4002000, 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.
