Description
CHAPS PUFFERAN® is a zwitterionic surfactant supplied at a minimum purity of 98 % for biochemistry applications. Identified by CAS number 75621-03-3 and empirical formula C₃₂H₅₈N₂SO₇, it has a molar mass of 614,9 g/mol and is widely used where mild, charge-balanced detergents are required in protein and membrane work. The material belongs to the zwitterionic surfactant class and supports solubilisation and stabilisation steps typical of biochemical sample preparation. Its defined assay and molecular identity help laboratories specify a consistent reagent for buffer systems, extraction protocols and related biochemistry procedures. CHAPS of this grade integrates into standard wet-chemistry and life-science bench practices whenever a min. 98 % zwitterionic detergent with the stated formula and molar mass is required.
This article is part of Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

Questions about CHAPS, PUFFERAN®, min. 98 %, for biochemistry, 5 g, plastic
What is this article?
CHAPS, PUFFERAN®, min. 98 %, for biochemistry, 5 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.
