ReproSil-Pur 300

High-Purity Silica HPLC Columns for Proteins and Large Biomolecules

The ReproSil-Pur 300 series is based on ultra-pure silica with a 300 Å pore size, specifically designed for the separation of proteins, large peptides, nucleic acids, and other high-molecular-weight biomolecules. The wide-pore structure ensures excellent accessibility for large analytes, maintaining high resolution and sharp peak shapes.

Available in a broad range of bonded chemistries (C18, C8, Phenyl, CN, etc.), the ReproSil-Pur 300 series provides tailored selectivity for reversed-phase, normal-phase, and aromatic separations. Robust bonding chemistry ensures reproducibility, durability, and long lifetimes even under demanding chromatographic conditions such as elevated temperatures and extended gradient runs.

The ReproSil-Pur 300 series combines high-purity silica with wide-pore design – the reliable choice for laboratories analyzing proteins and other large biomolecules by HPLC.
