Description
Tris-hydrochloride buffer is supplied as a concentrated 3 M buffer solution at pH 8.8 for analytical chemistry and laboratory protocols requiring a strong, defined Tris-based alkaline buffer. Meeting Reag. Ph. Eur. 4.1.3 requirements, it is suited to pharmacopoeia-related buffering, dilution to working strength, and pH stabilisation where reproducible starting material matters. The aqueous solution has a density of approximately 1 g/cm³ and a boiling point of 100 °C. Presented in a 1 l plastic container, the pack size supports stock preparation, shared laboratory use, and repeated aliquoting for downstream methods. This grade from manufacturer Carl ROTH belongs to the special pH-buffer solutions aligned with Ph. Eur. 4.1.3, offering a convenient alternative to preparing high-molarity Tris-HCl from solid reagents. Laboratories can dilute or apply the solution according to validated procedures while maintaining consistent buffer identity and pH target. Use appropriate personal protective equipment and standard chemical-handling controls for concentrated buffer solutions.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Tris-hydrochloride , buffer solution 3 M pH 8.8 , 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.
