Description
Phosphate buffer solution pH 5.6 is a ready-to-use analytical buffer prepared according to Reag. Ph. Eur. 4.1.3 for controlled pH work in pharmaceutical and laboratory settings. With a defined target of pH 5.6, it supports reproducible titration, dissolution testing, and method development where European Pharmacopoeia buffer systems are required. The aqueous solution has a density of approximately 1 g/cm³ and a boiling point of 100 °C, making it straightforward to handle under standard bench conditions. Supplied in a 1 l plastic bottle, the pack size suits routine analytical workflows and multi-sample sequences without frequent replenishment. This buffer solution from manufacturer Carl ROTH is intended for special pH-buffer applications listed under Ph. Eur. 4.1.3 and fits laboratories that need consistent phosphate-based media for quality control, research, and pharmacopoeial compliance checks. Clear labelling and a practical plastic container support safe storage and dispensing in analytical chemistry environments.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Phosphate buffer solution pH 5.6, Reag. Ph. Eur. 4.1.3, 4011200, 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.
