Welch Materials Xtimate Bio SEC Columns

Xtimate Bio SEC Chromatography Column employs ultrapure silica gel as its matrix for size exclusion chromatography. Its stationary phase consists of ultrapure silica gel microspheres with a uniformly nano-thick layer of hydrophilic polymer bonded to their surfaces.

Welch Materials employs a unique surface modification technology, ensuring the complete and uniform bonding of the polymer nanolayer to the silica gel surface. This extensive coverage significantly reduces the nonspecific adsorption of biological samples within the silica gel packing. The Xtimate Bio SEC column also exhibits excellent stability and batch reproducibility. Its primary application areas include biomolecules such as proteins, nucleic acids, peptides, oligonucleotides, bacteria, viruses, and more.

Features

Stationary phase consists of hydrophilic polymer with a uniform nano-thick layer bonded to the surface of ultrapure silica gel microspheres.
Available in 5μm and 3μm silica gel microspheres, catering to high throughput testing requirements.
Offers products with different pore size parameters to meet diverse needs for the separation of biomolecules.
Minimal nonspecific adsorption of biological molecules.
Demonstrates excellent stability and reproducibility across batches.
