Description
Phosphate buffer solution 0,1 M pH 6.5 is a ready-to-use analytical reagent prepared according to Reag. Ph. Eur. 4.1.3 for controlled pH work in the laboratory. With a nominal concentration of 0,1 M and a target pH of 6,5, it supports reproducible buffering in pharmaceutical, chemical and quality-control applications that require European Pharmacopoeia-aligned reagents. The aqueous solution exhibits a density of approximately 1 g/cm³ and a boiling point of 100 °C, consistent with dilute phosphate buffer systems. Supplied in a 1 l pack and weighing 1,300 kg, the product is convenient for routine bench use and method development. This buffer solution from manufacturer Carl ROTH is intended for laboratories performing titrations, sample preparation, instrument calibration and other procedures where a stable near-neutral phosphate medium is specified. Clear labelling of concentration and pH facilitates traceability within analytical workflows and documentation under Ph. Eur. chapter 4.1.3. Use according to established laboratory protocols for buffer handling and pH verification.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Phosphate buffer solution 0.1 M pH 6.5, Reag. Ph. Eur. 4.1.3, 4010800, 1 l 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.
