MilliporeSigma™ Supelco™ Unix™ SEC Guard Cartridge with Holder SEC-200, 1.8 μm Particle Size

Utilizing proprietary surface technologies, Unix™ SEC-300 phase is made of uniform, hydrophilic, and neutral nanometer thick films chemically bonded to high purity and mechanically stabilized silica with the particle size of 1.8 μm. The combination of small particle size and large pore volume of Unix SEC-300 renders the highest separation effciency and resolution of analytes. The well controlled surface chemisty results in excellent lot-to-lot reproducibility. The unique bonding chemistry, coupled with the maximized bonding density, allows Unix SEC-300 to provide high stability and negligible non-specific interactions. Typical applications for the Unix SEC-300 columns include separation and analysis of biological molecules and water-soluble polymers.
