Description
Tris(hydroxymethyl)aminomethane buffer solution pH 8.3 is a ready-to-use analytical buffer conforming to Reag. Ph. Eur. 4.1.3 for stable alkaline conditions in pharmaceutical testing and laboratory analysis. Delivered in a 1 l plastic pack, this special buffer solution supports titration, calibration support, and routine procedures that demand a defined pH of 8.3. Reported physical properties include a density of approximately 1 g/cm³ and a boiling point of 100 °C, consistent with aqueous buffer systems employed in quality-control and method-development settings. The product is positioned within the Ph. Eur. 4.1.3 pH-buffer family and suits laboratories that rely on pharmacopoeial reagents for reproducible results. Available from manufacturer Carl ROTH, it fits smoothly into analytical chemistry workflows for buffering, sample handling, and related applications. The 1 l pack size is practical for higher-throughput benches and shared laboratory stocks where larger working volumes reduce refill frequency. Categories cover analytical chemicals and special buffer solutions intended for European Pharmacopoeia-aligned practice in daily laboratory operations.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Tris(hydroxymethyl)aminomethane, buffer solution pH 8.3, 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.
