Description
TES, PUFFERAN®, min. 99 % is a zwitterionic biological buffer intended for molecular biology and related life-science applications. Identified by CAS number 7365-44-8, empirical formula C₆H₁₅NO₆S and molar mass 229,2 g/mol, it provides a defined chemical basis for preparing stable buffer solutions. This from manufacturer Carl ROTH delivers the PUFFERAN® quality grade for laboratory buffer work, including enzymatic reactions, sample handling and other molecular biological procedures that depend on controlled pH. TES is widely recognised among Good’s buffers and fits reagent portfolios used in research and analytical laboratories. EG nr. 230-906-3 supports clear substance identification for documentation and quality systems. The compact pack size suits method optimisation, pilot preparations and routine bench use where modest quantities are preferred. Consistent purity specification helps maintain reproducible buffer performance across experimental series in molecular biology workflows.
This article is part of Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

Questions about TES, PUFFERAN®, min. 99 %, 10 g, plastic
What is this article?
TES, PUFFERAN®, min. 99 %, 10 g, plastic 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.
Which category should I open next?
