Description
Tris(hydroxymethyl)aminomethane sodium chloride buffer solution pH 7.4 is a ready-to-use special buffer conforming to Reag. Ph. Eur. 4.1.3 for analytical chemistry and pharmacopoeial applications. Based on tris(hydroxymethyl)aminomethane with sodium chloride, it maintains a stable pH of 7.4 and is intended for procedures that require controlled buffering capacity and ionic strength. Reported physical properties include a density of about 1 g/cm³ and a boiling point of 100 °C, reflecting its aqueous character. Packed as a 1 l unit, the solution is practical for everyday laboratory use in quality control, method development and sample conditioning. This buffer solution from manufacturer Carl ROTH belongs to the Ph. Eur. 4.1.3 pH-buffer series used in European Pharmacopoeia-related work. Consistent composition supports reproducible results in titrations, dilutions and instrument calibration steps where a neutral-range buffer is specified. The one-litre presentation balances usable volume with straightforward handling in regulated and research laboratory environments.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Tris(hydroxymethyl)aminomethane, sodium chloride buffer solution pH 7.4, 1 l 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.
