Buffer solution pH 5.5 is a ready-to-use analytical reagent conforming to Reag. Ph. Eur. 4.1.3 for controlled pH work in pharmaceutical and general laboratory analysis. It provides a defined pH of 5.5 and supports methods that rely on stable buffering capacity, including sample preparation, titrations and instrument verification. Physical data include a density of approximately 1 g/cm³, a boiling point of 100 °C and a flash point above 60 °C, consistent with an aqueous buffer matrix. The solution is supplied in a practical 1 l plastic pack suited to routine bench use and quality-control workflows. Prepared as a special pH-buffer solution according to European Pharmacopoeia chapter 4.1.3, it is intended for laboratories that require reproducible ionic conditions at pH 5.5. This buffer from manufacturer Carl ROTH fits analytical chemistry applications where a reliable, pharmacopoeia-aligned medium is needed without further adjustment. Clear labelling and a convenient pack size help streamline daily laboratory handling and documentation.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Buffer solution pH 5.5
What is this article?
Buffer solution pH 5.5 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 Chemicaliën.
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.
Which category should I open next?
