Description

XK columns are constructed of robust borosilicate glass, which exhibits excellent chemical resistance and is compatible with aqueous solutions and most organic solvents used in liquid chromatography of macromolecules. The clear tubes allow for visual inspection of the media bed and are available in a broad range of column dimensions for use with many different purification needs.

Column packing can be performed using either a packing reservoir or an extra column tube attached with a packing connector. The QuickLock mechanism of the adapter shaft facilitates rapid and easy movement of the adapter, simplifying adjustments of the bed height, disassembly, and cleaning. The design of the adapter plunger gives a uniform flow, which maintains the integrity of the packed bed during operations.

• Plunger design to ensure a homogeneous buffer distribution and reproducible packing
• Adapter QuickLock mechanism that facilitates column handling and cleaning
• Fittings for direct connection to chromatographiy systems
• Cooling jacket for sensitive purifications
• Extensive range of spare parts available, facilitating maintenance
