Description
Tween® 80, Ph.Eur. is a non-ionic detergent and surfactant widely used in biochemistry and life-science laboratories. Registered under CAS number 9005-65-6, it shows a density range of 1,06 to 1,09 g/cm³, a flash point above 113 °C and a boiling point above 100 °C. Eur. specification, this grade is suitable for solubilisation, emulsification and protein or membrane work where a controlled detergent is required. Tween® 80 is a standard reagent in biochemical detergent sets for sample preparation, assay formulation and related laboratory procedures. size supports routine bench use and medium-scale preparations while remaining practical for inventory control. Clear physical property data assist method setup and safety assessment in everyday laboratory handling. Laboratories seeking a Ph.Eur.-grade polysorbate 80 for biochemistry workflows will find this presentation aligned with common detergent applications.

Questions about Tween® 80, Ph.Eur., 250 g, plastic
What is this article?
Tween® 80, Ph.Eur., 250 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 Microbiologie.
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.
