Description
Tris-sodium acetate-sodium chloride buffer solution pH 7.4 is a ready-to-use special buffer prepared in accordance with Reag. Ph. Eur. 4.1.3 for analytical and pharmacopoeial laboratory work. It provides defined buffering at pH 7.4 through a combination of tris, sodium acetate and sodium chloride, supporting methods that need stable pH control near physiological neutrality. Physical data include a density of approximately 1 g/cm³ and a boiling point of 100 °C, consistent with an aqueous buffer matrix. The solution is supplied in a practical 1 l plastic pack suited to routine bench use in quality control, sample preparation and instrument-related workflows. This buffer from manufacturer Carl ROTH forms part of the dedicated Ph. Eur. 4.1.3 pH-buffer range for European Pharmacopoeia-oriented testing. Laboratories value the clear composition and reproducible behaviour when establishing or verifying analytical conditions. The one-litre format offers a convenient working volume while remaining easy to handle and store within standard chemical laboratory organisation.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Tris- sodium acetate- sodium , chloride buffer solution pH 7.4, 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.
