Ordering Information

UniSil® reversed-phase media has uniformed particle size,  high mechanical strength, high bonding density, and good end-capping, so it has excellent physical and chemical properties, which are reflected in high column efficiency and low back pressure, wide pH tolerance range, which ultimately manifests the advantages of high chromatographic purification process load, good selectivity, good resolution, high efficiency, long life, and low purification cost.  

Nanomicro Technology UniSil® reversed-phase chromatography silica gel packing products have a complete range, which can meet the various needs of laboratory analytical high-performance liquid chromatography (UPLC, HPLC) analysis and industrial preparative high-performance liquid chromatography (Prep-HPLC), and has been widely used Used in chromatographic analysis and industrial production of various organic compounds, natural products, fermentation and semi-synthetic antibiotics and protein macromolecules.  

Nanotech reversed-phase chromatography silica gel fillers can provide UniSil® reversed-phase chromatography silica gel fillers with multiple functional groups including C1, C4, C8, C18, C18 AQ, C18 Polar, C30, Phenyl, etc. according to the surface modification form. It can meet the requirements of reversed-phase chromatographic analysis, preparation, separation and purification of different types of mixture samples, and can provide product customization for special applications.
