Description
HEPPSO is a high-purity biological buffer in the PUFFERAN® grade with a minimum purity of 99 %. It is defined by CAS number 68399-78-0, the empirical formula C₉H₂₀N₂O₅S and a molar mass of 289,33 g/mol. This zwitterionic Good’s-type reagent is used in molecular biology and biochemistry whenever stable pH control is required during sample preparation, electrophoresis, nucleic-acid work or enzymatic assays. The material is HEPPSO from manufacturer Carl ROTH is chosen by laboratories that prefer buffers with limited metal-ion interaction and reproducible performance in sensitive life-science workflows. Typical applications include preparation of working buffer solutions for protein studies, cell-based assays and molecular biological protocols that depend on consistent ionic conditions. The PUFFERAN® quality level supports analytical and preparative tasks where batch-to-batch reliability matters. Researchers value the practical pack size for everyday laboratory use without unnecessary excess inventory, making this reagent a practical component of molecular biological buffer systems.
