Description
Phosphate buffer solution pH 6.8 is an analytical reagent prepared to Reag. Ph. Eur. 4.1.3 specifications for laboratories that require a defined phosphate buffer near neutrality. With a target pH of 6,8, it supports pharmaceutical testing, chemical analysis and quality-control work referencing European Pharmacopoeia buffer systems. The solution shows a density of approximately 1 g/cm³ and a boiling point of 100 °C, consistent with dilute aqueous phosphate preparations. Delivered in a 1 l plastic pack at a weight of 1,300 kg, it is practical for everyday bench applications including sample preparation, instrument verification and method support. This phosphate buffer solution from manufacturer Carl ROTH is designed for procedures in which a stable pH 6,8 phosphate medium is specified. Clear pH identification assists documentation and traceability within Ph. Eur. 4.1.3 workflows. Verify pH and handle the reagent according to established laboratory protocols before critical analytical steps.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Phosphate buffer solution pH 6.8, Reag. Ph. Eur. 4.1.3, 4003300, 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.
