BioBasic AX 5µm 20x2.1mm Javelin GuardS 4/Pack

The Thermo Scientific Javelin BioBasic AX Guard Columns 20x2.1mm, 5µm, are used to protect BioBasic HPLC columns with 2.1mm inner diameter installed. The Javelin guard columns can be screwed directly into the analytical HPLC column and no additional holder is required.

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.
