Description
Tris-hydrochloride buffer solution 0,05 M pH 7.5 is a ready-to-use special buffer intended for analytical and laboratory applications requiring controlled ionic strength and stable pH. Formulated as a Reag. Ph. Eur. 4.1.3 reagent at 0,05 M and pH 7.5, it provides a defined Tris-HCl system for standardised buffering in quality control, sample preparation and related procedures. The product is packed in a 1 l plastic container for convenient bench handling and direct use without additional dilution or adjustment. Density is approximately 1 g/cm³ and the boiling point is 100 °C, reflecting typical aqueous buffer behaviour. Laboratories following pharmacopoeial guidance can integrate this preparation into workflows that specify Tris-hydrochloride media at mild concentration. Available from manufacturer Carl ROTH within the pH-buffer solutions assortment aligned with Ph. Eur. 4.1.3, the clear liquid format supports reliable pH maintenance during analytical work. The litre pack size offers a practical balance of volume and manageability for routine laboratory consumption of 0,05 M Tris-HCl buffer at pH 7.5.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Tris-hydrochloride , buffer solution 0.05 M pH 7.5, 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.
