Description
Phosphate buffer solution pH 6.4 is a ready-to-use analytical reagent conforming to Reag. Ph. Eur. 4.1.3, developed for controlled buffering in pharmaceutical and laboratory procedures. Set at pH 6.4, it supports titrations, sample preparation, method validation and quality-control work carried out according to European Pharmacopoeia requirements. The aqueous buffer has a density of approximately 1 g/cm³ and a boiling point of 100 °C, making it suitable for routine bench use under typical laboratory conditions. Supplied in a 1 l plastic bottle, the pack size is practical for daily analytical sequences and specialised assays that need defined phosphate buffering. This solution from manufacturer Carl ROTH belongs to the Ph. Eur. 4.1.3 special buffer range used in analytical chemistry. Laboratories performing pharmacopoeial tests, reagent preparation or related analytical tasks can rely on its stated grade and physical properties to maintain stable pH conditions. The ready-to-use format reduces preparation steps while supporting consistent results across pharmaceutical testing and research environments.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Phosphate buffer solution pH 6.4, Reag. Ph. Eur. 4.1.3, 4002800, 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.
