Description
SDS ultra pure is a high-purity sodium dodecyl sulfate grade with a minimum assay of 99 %, supplied for electrophoresis as well as biochemistry and molecular biology workflows. Identified by CAS number 151-21-3 and EG number 205-788-1, it has the empirical formula C₁₂H₂₅NaO₄S and a molar mass of 288,38 g/mol. Key physical data include a flash point of 170 °C and a boiling point of 216 °C, supporting controlled handling in the laboratory. This detergent is widely used to denature proteins, solubilise membrane components and prepare samples for SDS-PAGE and related separation techniques. The material is Its defined purity and documented physicochemical profile make it a reliable choice when consistent detergent performance is required in life-science and analytical applications.
This article belongs on Detergents & surfactants, in Biochemicals & reagents.

Questions about SDS ultra pure, min. 99 %, for electrophoresis,, 100 g, plastic
What is this article?
SDS ultra pure, min. 99 %, for electrophoresis,, 100 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Detergents & surfactants, inside Biochemicals & reagents, in Life Science & Microbiology.
A laboratory detergent or surfactant, such as SDS, Tween or Triton, solubilises membranes and stops proteins sticking. The average chain length and the peroxide content matter, especially for a protein that a peroxide would damage. A cleaning detergent for glassware is a different product.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
