Description

The user-friendly design of XK columns ensures trouble-free operation with fittings for direct connection to ÄKTA design instruments or other high-performance liquid chromatography systems. The product family is based on a robust design for high reproducibility and accurate results. XK columns are compatible with aqueous solutions and most organic solvents used in liquid chromatography of macromolecules. XK empty columns provide reliable and reproducible separations. The tube material is of borosilicate glass, which allows for visual inspection of the resins bed. The columns are made of biocompatible materials that exhibit excellent chemical resistance. A broad range of column dimensions makes XK columns suitable for 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. An extensive range of spare parts is available, facilitating maintenance.

FAQs

Question: What diameter identifies the XK 26/70 chromatography column?

Answer:The column has a 26 mm internal diameter and a nominal 70 cm tube.

Question: How much packed medium fits the XK 26/70 with one adapter?

Answer:One-adapter operation provides approximately 281–344 mL of bed volume, corresponding to a 53–65 cm bed height.

Question: Is the XK 26/70 prepacked or supplied empty?

Answer:The column is supplied empty and requires separate packing media and a suitable chromatography system.

Application Note

The Cytiva XK 26/70 empty chromatography column combines a 26 mm internal diameter with a nominal 70 cm tube length for preparative laboratory protein separations. The larger bore provides more bed capacity than a 16 mm XK column at a comparable bed height, while retaining adjustable adapter control and a visible borosilicate glass column tube. With one adapter, the packed bed can occupy approximately 281–344 mL at a height of 53–65 cm. Its geometry supports size-exclusion and other resin-packed chromatographic workflows requiring intermediate sample or media capacity. The XK 26/70 is column hardware rather than a ready-to-run prepacked product; use a separately selected resin and verify packing quality, system flow limits, and column performance before sample processing.
