Description
TRIS solution is a pharmacopoeia-quality laboratory reagent specified as Reag. Ph. Eur., Chapter 4.1.1, under reagent number 1094201, with CAS number 77-86-1, empirical formula C₄H₁₁NO₃, EG nr. 201-064-4 and a molar mass (M) of 121,14 g/mol. The product belongs to chemicals in pharmacopoeia quality and to the reagents and volumetric standard solutions of the European Pharmacopoeia, specifically Reagents 4.1.1. It is supplied as a 100 ml fill in a plastic pack, a compact volume for analytical work that requires a defined Ph. Eur. Chapter 4.1.1 TRIS solution. Listed properties include a density (D) of approximately 1 g/cm³ and a boiling point (bp) of 100 °C. TRIS solution is offered from manufacturer Carl ROTH within the Reag. Ph. Eur. Chapter 4.1.1 series. Laboratories can confirm identity through the CAS number, empirical formula C₄H₁₁NO₃, molar mass 121,14 g/mol and EG nr. 201-064-4, together with the Reag. Ph. Eur. designation, Chapter 4.1.1 and number 1094201. The 100 ml plastic presentation, density near 1 g/cm³ and boiling point of 100 °C complete the published pack and physical profile.

Questions about TRIS solution, Reag. Ph. Eur., Chapter 4.1.1, 100 ml
What is this article?
TRIS solution, Reag. Ph. Eur., Chapter 4.1.1, 100 ml is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Biological buffers (Tris, HEPES, MOPS), inside Buffers & pH solutions, in Lab chemicals.
Tris, HEPES, MOPS and their relatives hold pH in a range that cells and proteins tolerate, with a pKa near the working pH. The useful range is roughly one unit either side of the pKa. A phosphate buffer and Tris are not interchangeable in a method that names one of them, because the ion itself has effects.
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.
