Description
Tween® 80 is a non-ionic surfactant supplied in extra pure quality for laboratory and life-science applications. Identified by CAS number 9005-65-6, the product shows a density in the range 1,06 to 1,09 g/cm³, a flash point above 113 °C and a boiling point greater than 100 °C. These physical characteristics make it suitable as a nutrient-media additive and dispersing agent in microbiology, where controlled wetting and solubilisation support culture preparation and sample handling. The material is packed as 25 g in glass, offering a practical bench-scale quantity for media formulation, emulsion work and routine laboratory protocols. Extra pure grade supports reproducible performance in research and quality-control settings that rely on consistent surfactant behaviour. Available from manufacturer Carl ROTH, Tween® 80 fits established workflows in microbiology and broader life-science reagent inventories. Documented density, thermal data and CAS identity facilitate specification checks and safe integration into standard operating procedures without unnecessary reformulation steps.
This article belongs on Detergents & surfactants, in Biochemicals & reagents.

Questions about Tween® 80, extra pure, 25 g, glass
What is this article?
Tween® 80, extra pure, 25 g, glass 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.
