Description
Tris-hydrochloride buffer is a ready-to-use buffer solution at 1,5 M concentration, adjusted to pH 8.8 for laboratory and analytical applications that need a defined alkaline Tris-based medium. Classified as Reag. Ph. Eur. 4.1.3, it is intended for work where pharmacopoeial buffer quality supports method consistency, sample preparation, and pH-controlled procedures. Physical data include a density of about 1 g/cm³ and a boiling point of 100 °C, reflecting its aqueous formulation. The product is packed as 500 ml in plastic, a practical volume for individual benches, method development, or moderate throughput without large bulk handling. Offered by manufacturer Carl ROTH within the special buffer solutions range for Ph. Eur. 4.1.3, this Tris-HCl preparation helps laboratories standardise alkaline buffering steps while reducing on-site weighing and pH adjustment. Handle and store in line with good laboratory practice for concentrated buffer concentrates and solutions of this class.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Tris-hydrochloride , buffer solution 1.5 M pH 8.8, 500 ml, 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.
