Seplife RP LXMS-15(100) Reversed-Phase Medium, 15 µm (CAT#: STEM-BC-3118-ZJF)

This reversed-phase medium is designed for high-resolution separation of small molecules, peptides, and low-molecular-weight proteins. It uses a porous polystyrene-divinylbenzene matrix. The 15 µm particles provide efficient mass transfer and improved chromatographic resolution. A 100 Å average pore size is suited to small molecules and smaller peptides. The polymeric matrix provides a broader pH range than conventional reversed-phase silica. High rigidity permits operation at elevated pressure and fast flow. The medium is compatible with common aqueous buffers and many organic solvents. High dynamic loading supports productive preparative purification. It can be stored in 20% ethanol between uses.
