UniSil C8 Reversed Phase Bulk Media, UniSil 8-200 C8 (CAT#: STEM-C-3173-ZJF)

UniSil reversed-phase bulk media deliver outstanding physical and chemical properties, including uniform particle size, high mechanical strength, strong bonding density, effective end-capping, excellent column efficiency, low back pressure, and broad pH tolerance. These features provide significant benefits, such as high purification capacity, superior selectivity, sharp resolution, enhanced efficiency, long lifespan, and reduced operational costs.
This reversed-phase chromatography silica gel is available in a wide range of particle sizes and pore sizes, designed to address diverse needs from laboratory-scale analytical high-performance liquid chromatography (UPLC, HPLC) to industrial preparative and process-scale chromatography (Prep-HPLC). It is well-suited for the separation and purification of organic compounds, natural products, fermentation products, semi-synthetic antibiotics, and protein macromolecules. Customization options are available for specific applications.
The C8 phase is another widely used reversed phase, offering similar selectivity to the C18 phase but with shorter retention times, making it ideal for specific chromatographic requirements.
