Sepax Technologies Inc Sepax HPLC Column PolyRP-100, Guard cartridge with holder, 10 µm, 4 x 10 mm
GP-C8 phase is synthesized with monomeric and fully endcapped chemistry. The uniform octyl stationary phase allows high efficiency with lower hydrophobicity compared to ODS phase. GP-C8 phase is suitable for separating compounds with a wide range of hydrophobicity. It is highly recommended for separating the compounds which are too strongly retained on C18 phases.
Sepax Technologies Inc Sepax HPLC Column PolyRP-300, Guard cartridge with holder, 5 µm, 4 x 10 mm
GP-C8 phase is synthesized with monomeric and fully endcapped chemistry. The uniform octyl stationary phase allows high efficiency with lower hydrophobicity compared to ODS phase. GP-C8 phase is suitable for separating compounds with a wide range of hydrophobicity. It is highly recommended for separating the compounds which are too strongly retained on C18 phases.
Sepax Technologies Inc Sepax HPLC Column HPLC GUARD Column, BioMix SEC-300, 3 µm, 4.6 x 50 mm
Utilizing proprietary surface technologies and 3 µm particle size, BioMix-300 phase is made of uniform, hydrophilic, and neutral nanometer thick films chemically bonded on the high purity and enhanced mechanical stability silica. The proprietary surface technologies allow the chemistry of thin film formation to be well controlled, which results in high column-to-column reproducibility. The nature of the chemical bonding and the uniformity of the thin film benefit BioMix-300 phase with high stability. BioMix-300 resin is produced from 3 µm spherical silica particles with a pore size of 300 Å. BioMix-300 columns are packed with a proprietary slurry technique to achieve uniform and stable packing bed density for maximum column efficiency. BioMix-300 phase is designed to ensure highest resolution and maximum recovery for a broad range of analytes such as bispecific mAb, hydrophobic samples etc.
Sepax Technologies Inc Sepax HPLC Column Bio-C18, 3 µm, 300 Å, 2 x 10 mm
Wide range of pore sizes and high compatibility with 100% aqueous phases make Bio-C18 columns ideal for high resolution mapping of peptides and separation of natural and synthetic peptides and small proteins. The specially designed surface bonding chemistry and the pore sizes allow for extended retention and selectivity for polar and hydrophilic compounds, such as peptides and amino acids. C18 monolayer formed by special bonding chemistry does not collapse in pure aqueous solution.
Sepax Technologies Inc Sepax HPLC Column GP-C8, 3 µm, 120 Å, 4 x 10 mm
GP-C8 phase is synthesized with monomeric and fully endcapped chemistry. The uniform octyl stationary phase allows high efficiency with lower hydrophobicity compared to ODS phase. GP-C8 phase is suitable for separating compounds with a wide range of hydrophobicity. It is highly recommended for separating the compounds which are too strongly retained on C18 phases.
