Phosphate buffer solution pH 7.5 0,2 M is a ready-to-use special buffer solution for analytical chemistry and pharmacopoeial laboratory applications. The preparation delivers a 0,2 M phosphate system at pH 7.5 and carries the designation Reag. Ph. Eur. 4.1.3, making it appropriate where European Pharmacopoeia-aligned buffers are required. Density is approximately 1 g/cm³ and the boiling point is 100 °C, consistent with dilute aqueous media. Packed as a 1 l unit, the solution provides a practical volume for routine buffering, sample conditioning, and controlled pH work at the bench. Available from manufacturer Carl ROTH within the Ph. Eur. 4.1.3 pH-buffer solutions portfolio, it supports reproducible conditions in titrations, analytical sample preparation, and related procedures that specify a 0,2 M phosphate buffer at pH 7.5. Users benefit from a defined concentration and pH without intermediate salt weighing or adjustment steps. The one-litre format fits standard laboratory inventory practices and facilitates straightforward dispensing during daily analytical workflows.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Phosphate buffer solution pH 7.5 0,2 M, 1 l
What is this article?
Phosphate buffer solution pH 7.5 0,2 M, 1 l is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in pH-buffers & geleidbaarheidsstandaarden, inside Buffers & pH-oplossingen, 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.
