Description
Phosphate buffer solution 0,1 M pH 7.0 is an analytical reagent buffer specified as Reag. Ph. Eur. 4.1.3 for laboratory use. It combines a 0,1 M phosphate concentration with a defined pH of 7.0, making it suitable where a neutral pharmacopoeia-aligned phosphate system is required. Physical data include a density of approximately 1 g/cm³ and a boiling point of 100 °C, in line with aqueous buffer media. The product is supplied in a 1 l pack with a weight of 1,300 kg, supporting routine dispensing in analytical workflows. This phosphate buffer solution from manufacturer Carl ROTH belongs to the special pH-buffer solutions prepared according to European Pharmacopoeia 4.1.3. Such reagents are applied in analytical chemistry for sample handling, method work and other procedures that call for controlled pH near neutrality. The 0,1 M strength and pH 7.0 setting help laboratories maintain consistent buffering conditions when monographs or internal methods reference this composition. Clear labelling of concentration and pH supports traceable use alongside other Ph. Eur. buffer reagents in quality-focused environments.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Phosphate buffer solution 0.1 M pH 7.0, Reag. Ph. Eur. 4.1.3, 4008200, 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.
