Tween 80 (Polyoxyethylenesorbitan Monooleate), 4L, is a highly effective nonionic detergent used in laboratories for protein solubilization, emulsification, and buffer preparation. The 4L size is ideal for large-scale applications, including protein extraction, enzyme assays, and creating emulsions for biochemical and pharmaceutical research. Tween 80 is widely used in studies involving cell cultures, immunology, and drug formulations where mild and non-disruptive detergents are required to maintain the integrity of sensitive biological macromolecules. The 4L container ensures that laboratories with high usage can maintain a sufficient supply of this versatile emulsifying agent.
