Description
Tris(hydroxymethyl)aminomethane buffer solution pH 8.1 is a ready-to-use analytical buffer prepared to Reag. Ph. Eur. 4.1.3 for controlled alkaline conditions in pharmaceutical and laboratory workflows. Offered in a 100 ml plastic pack, this special buffer solution supports reproducible titration, method development, and routine analytical procedures where a stable pH of 8.1 is required. Physical data include a density of approximately 1 g/cm³ and a boiling point of 100 °C, typical of aqueous buffer systems used in quality-control environments. The reagent belongs to the Ph. Eur. 4.1.3 pH-buffer range and fits laboratories that standardise on pharmacopoeial buffer solutions for consistency across assays. Supplied by manufacturer Carl ROTH, it integrates readily into analytical chemistry benches for buffering, sample preparation support, and related applications. The compact 100 ml format suits method validation, teaching laboratories, and smaller-scale work where moderate volumes are preferred without bulk handling. Categories span analytical chemicals and special buffer solutions aligned with European Pharmacopoeia practice for reliable day-to-day use.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Tris(hydroxymethyl)aminomethane, buffer solution pH 8.1, 100 ml, 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.
