Description
HEPBS is a high-purity biological buffer offered as PUFFERAN® grade with a minimum purity of 99 %. Characterised by CAS number 161308-36-7, the empirical formula C₁₀H₂₂N₂O₄S and a molar mass of 266,36 g/mol, this zwitterionic compound serves as a molecular biological buffer in life-science laboratories. It supports reliable pH control in electrophoresis, enzyme assays, nucleic-acid handling and related biochemical workflows. The product is HEPBS from manufacturer Carl ROTH is selected where Good’s-type buffers are preferred for their favourable interaction profile with biological macromolecules and metal ions. Applications span protein studies, cell-culture media adjustment and general molecular biology protocols that demand stable ionic conditions. The PUFFERAN® designation indicates a quality level suited to demanding analytical and preparative work. Laboratories appreciate the compact pack size for routine use and method optimisation while maintaining consistent buffer performance across experiments in molecular biological buffer systems.

Questions about HEPBS, PUFFERAN®, min. 99 %, 25 g, plastic
What is this article?
HEPBS, PUFFERAN®, min. 99 %, 25 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.
