ReproSil-Pur 1000 Si

Ultra-Wide-Pore Silica Column for Normal-Phase Analysis of Large Biomolecules

ReproSil-Pur 1000 Si is an unbonded, high-purity silica HPLC column with a 1000 Å ultra-wide pore structure, designed for normal-phase and adsorption chromatography of very large biomolecules. The extensive pore system ensures excellent accessibility for intact proteins, antibodies, nucleic acids, and polysaccharides, while the active silanol surface provides strong polar interactions.

Compared to conventional silica phases, ReproSil-Pur 1000 Si allows improved mass transfer and resolution for ultra-large analytes, making it particularly valuable for biopharmaceutical and biochemical applications. Its high-purity silica guarantees reproducibility, sharp peak shapes, and robustness under demanding conditions.

ReproSil-Pur 1000 Si combines ultra-wide-pore silica with strong polar selectivity – the dependable choice for laboratories analyzing very large biomolecules by normal-phase HPLC.

Key Features:

  • Unbonded, high-purity silica stationary phase

  • 1000 Å ultra-wide pore size for very large biomolecules

  • Strong polar interactions for normal-phase chromatography

  • Excellent reproducibility and sharp peak shapes

  • Available particle size: 5 µm
