Description
Phosphate buffer solution pH 3.2 R1 is a pharmacopoeial analytical buffer meeting Reag. Ph. Eur. 4.1.3 for applications that require the R1 grade at pH 3.2. Density is approximately 1 g/cm³ and the boiling point is 100 °C, making the aqueous solution suitable for controlled pH work in titrations, sample preparation and related laboratory procedures. Offered as a 1 l plastic pack, it is practical for quality-control and research laboratories that need a ready-to-use phosphate buffer under European Pharmacopoeia conditions. Manufactured by Carl ROTH to the Ph. Eur. 4.1.3 phosphate buffer pH 3.2 R1 specification, it supports monographs and internal methods that name this reagent. The defined acidic pH and phosphate matrix help dissolve or dilute samples, adjust media and stabilise analytical systems with consistent buffering capacity. Use this solution wherever Ph. Eur. phosphate buffer pH 3.2 R1 is required to maintain procedural alignment and dependable performance across analytical series.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Phosphate buffer solution pH 3.2 R1
What is this article?
Phosphate buffer solution pH 3.2 R1 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.
