Non-Ionic Surfactant for Laboratory, Biochemical, and Formulation Applications
VWR Polysorbate 20 (Polyoxyethylene (20) sorbitan monolaurate, C₅₈H₁₁₄O₂₆) is a reagent-grade, non-ionic surfactant widely used in biochemical assays, sample preparation, and emulsion stabilization. Known for its high solubility in water and gentle surfactant action, Polysorbate 20 is often applied in protein-based experiments, ELISA buffers, and biological reagent formulations.
This product is stringently tested for enzyme activity (RNase, DNase, and protease-free), making it suitable for sensitive molecular biology and cell-based applications. It is supplied in high-quality, sealed containers for consistent laboratory performance.
