Tween 80 (Polyoxyethylenesorbitan Monooleate), 18.9L, is a bulk nonionic surfactant and emulsifier used in a variety of laboratory applications. This large container is suitable for institutions and research laboratories that require large volumes of Tween 80 for continuous use in protein and lipid solubilization, as well as in the preparation of stable emulsions for biochemical assays. It is commonly employed in molecular biology, immunology, and pharmaceutical research to enhance the solubility of hydrophobic molecules while maintaining their structural integrity. The large volume ensures that large-scale research projects or institutional laboratories can maintain a steady supply of this versatile reagent.
