Description
Phosphate buffer solution pH 2.0 is a ready-to-use analytical buffer prepared according to Reag. Ph. Eur. 4.1.3 for acidic phosphate-buffered laboratory applications. Provided as a 1 l plastic pack, the solution exhibits a density of about 1 g/cm³ and a boiling point of 100 °C, supporting straightforward handling in analytical chemistry environments. It belongs to the special pH-buffer solutions Ph. Eur. 4.1.3 group and is intended where a defined phosphate system at pH 2.0 is required for calibration, quality control, or pharmacopoeial testing. The product is available from manufacturer Carl ROTH under catalogue reference 4007900 for professional laboratory use. Clear physical parameters—density approximately 1 g/cm³ and boiling point 100 °C—facilitate incorporation into standard methods and documentation. The 1 l plastic unit offers convenient storage and dispensing for laboratories that depend on consistent Ph. Eur. phosphate buffers to maintain reproducible acidic pH conditions across analytical workflows.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Phosphate buffer solution pH 2.0, Reag. Ph. Eur. 4.1.3, 4007900, 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.
