Description
Tris-sodium acetate buffer is an aqueous buffer solution set to pH 8.0 for laboratory use where a combined Tris and sodium acetate system is required. Presented as Reag. Ph. Eur. 4.1.3 material, it belongs to the group of special pH-buffer solutions used in analytical chemistry under pharmacopoeial chapter 4.1.3. The solution has a density of approximately 1 g/cm³ and a boiling point of 100 °C. Packed as 1 l in plastic from manufacturer Carl ROTH, it is convenient for ongoing analytical and sample-preparation work. Tris–acetate-type buffers are applied when mild ionic strength and stable alkaline pH support nucleic-acid handling, chromatographic steps, or general biochemical procedures that benefit from acetate alongside Tris. Supplying the buffer ready at pH 8.0 reduces manual adjustment and helps laboratories keep preparation steps reproducible. This Tris-sodium acetate buffer solution offers a clearly specified option for teams that need a Ph. Eur.-aligned special buffer for controlled pH environments in research, method development, and routine quality-control laboratories.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Tris-sodium acetate buffer, solution pH 8.0, 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.
