BioBasic 4 5µm 250x212mm Prep Column

The BioBasic 4 HPLC column 250x21.2mm, 5µm, is made from wide-pore 300Å silica with a C4 phase. The weaker hydrophobic surface is designed for larger proteins and sensitive biomolecules. The low retention pressure facilitates complete elution and reduces irreversible adsorption. BioBasic 4 is used particularly for intact proteins, antibody fragments and large peptides.

Features and Benefits

• Wide-pore silica phases for biomolecules
• Reverse-phase, ion exchange, and size exclusion
• Graded hydrophobicity from C18 to C4
• SEC pore sizes for different molecular weights
• Analytical and biocompatible applications

Additional Information

BioBasic includes large-pore silica-based phases for proteins, peptides, oligonucleotides, and other biomolecules. Alkyl, phenyl, and cyano surfaces cover reverse-phase chromatography; AX and SCX cover charge separation; and SEC 60 through SEC 1000 cover various hydrodynamic size ranges. In SEC, pore size and the calibration-dependent fractionation range are critical; in ion exchange, pH and ionic strength determine binding.
