Description
Phosphate buffer solution pH 3.2 is a specialised Reag. Ph. Eur. 4.1.3 buffer for analytical and pharmaceutical laboratories needing precise control in the mildly acidic range. With a density of about 1 g/cm³ and a boiling point of 100 °C, this aqueous reagent is ready for use in titrations, sample preparation, dissolution work and method development that cite phosphate buffer pH 3.2. Supplied in a 1 l plastic container, it fits routine quality-control and research settings where stable buffering and straightforward handling are required. The product from manufacturer Carl ROTH is prepared according to the European Pharmacopoeia 4.1.3 framework, supporting compliance with monographs that specify this buffer. Its defined pH and phosphate composition aid consistent media adjustment, analyte stabilisation and preparation of test solutions. Select this buffer when procedures call for Ph. Eur. phosphate buffer pH 3.2 to promote method alignment and reproducible results from batch to batch in analytical chemistry workflows.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Phosphate buffer solution pH 3.2, Reag. Ph. Eur. 4.1.3, 4008100, 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.
