MSilica Based GP and HP Bulk Sorbents
Sepax manufactures wide range of silica based media with the particle size selection of 5, 10, 15 and 20 µm spherical particles, 20-40 µm and 40-60 µm irregular particles. Their pore size selection is 60, 120, 200, 300 and 500 Å. The bonding chemistry is from regular C18, C8, C4, Phenyl, Cyano, Amino, Diol, Pyridine, SCX and SAX to any custom-synthesis. The controlled manufacturing process guarantees high batch-to-batch reproducibility. Their high surface area and high mechanical strength enable those media ideal for preparative separation and purification.

Silica Based Bulk Sorbents
Sepax manufactures irregular silica sorbents with the particle size selection of 20-40 and 40-60 µm, the surface area of 550 m²/g, and the pore size of 60 Å. The bonding chemistries are from regular C18, C8, C4, Phenyl, Cyano, Amino, Diol, SCX and SAX to any custom-synthesis. The controlled manufacturing process guarantees high batch-to-batch reproducibility. Their high surface area and high mechanical strength enable those media ideal for solid phase extraction, flash chromatography, industrial scale separation and purification.

Polymeric Bulk Media
Sepax manufactures PS/DVB and acrylate polymer resins with the particle size selection of 5, 10, 15, 30, 50 and 100 µm and the pore size selection of 100, 300, 500 and 1000 Å. The spherical PS/DVB particles are highly cross-linked for enhanced mechanical stability. The PS/DVB resins with high hydrophobicity are used as the reversed phase separation media. The cross-linked polyacrylate resins are hydrophilic. Using PS/DVB and polyacrylate particles as the supports, SCX, WCX, SAX, and WAX ion-exchange media are prepared. SCX media is a strong cation exchanger with sulfonate functional groups. WCX is a weak cation exchanger with carboxylate functional groups. SAX is a strong anion exchanger with quaternary ammonium functional groups. WAX is a weak anion exchanger with tertiary amine functional groups. The controlled manufacturing process guarantees high batch-to-batch reproducibility. Their high surface area and high mechanical strength enable those media ideal for preparative separation and purification of proteins, peptides, nucleic acids, antibiotics, and pharmaceuticals.
