Zenix
Made of 3µm silica particles, Zenix SEC packing is a breakthrough technology for size exclusion chromatography. Combination of 3 µm silica particle size and proprietary surface technology enables highest separation efficiency and resolution for biological molecules and water soluble polymers. Available pore sizes of Zenix packings are 100, 150 and 300Å.
