UniSil C4 Reversed Phase Bulk Media, UniSil 3-200 C4 (CAT#: STEM-C-3177-ZJF)

UniSil reversed-phase bulk media feature exceptional physical and chemical properties, including uniform particle size, high mechanical strength, strong bonding density, effective end-capping, superior column efficiency, low back pressure, and broad pH tolerance. These attributes offer significant advantages, such as enhanced purification capacity, excellent selectivity, high resolution, optimal efficiency, extended lifespan, and cost-effective operation.
The reversed-phase chromatography silica gel is available in a comprehensive range of particle and pore sizes to accommodate diverse requirements, from laboratory-scale analytical high-performance liquid chromatography (UPLC, HPLC) to industrial preparative and process-scale chromatography (Prep-HPLC). It is ideally suited for the separation and purification of organic compounds, natural products, fermentation products, semi-synthetic antibiotics, and protein macromolecules. Customization options are available for specialized applications.
The C4 phase offers moderate retention for both hydrophobic and polar compounds, making it particularly suitable for reversed-phase chromatography (RPC) separation of a variety of biomolecules.
