Description
Tween® 40 is a Ph.Eur.-grade material supplied for laboratory and life-science use, identified by CAS number 9005-66-7. Manufacturer data list a density of 1,08 g/cm³ and a flash point above 113 °C, giving clear physical reference points for handling, storage planning and method documentation. The product is As a recognised Tween® surfactant grade meeting Ph.Eur. requirements, it fits workflows that specify pharmacopoeial quality for non-ionic detergents. Density and flash-point values support risk assessment and process design, while the CAS number anchors identity in purchasing and inventory systems. balances bench-scale consumption with economical restocking for shared laboratory stocks. Tween® 40 from manufacturer Carl ROTH is positioned for life-science and biochemistry detergent use where Ph.Eur. alignment and transparent physical data matter. Laboratories can integrate the stated density, flash point and CAS information directly into SOPs and material registers, with the plastic pack supporting clean, practical day-to-day handling.

Questions about Tween® 40, Ph.Eur., 250 g, plastic
What is this article?
Tween® 40, 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 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.
Which category should I open next?
