Answer:20 cm for the XK 50/20 chromatography column.
Answer:No. It is the glass inner column tube; the acrylic jacket is a separate accessory.
Answer:Use the tube length specified for the assembled column and desired bed height; the two lengths are different parts.
The Cytiva XK 50/20 Glass Chromatography Column Tube is a 20 cm spare glass tube for the XK 50/20 chromatography column assembly. Its nominal 50 mm internal diameter accommodates the packed resin bed when assembled with the matching adapters, end pieces and seals. Transparent glass makes it possible to examine packing behavior, bed settling and visible bubbles during chromatographic method setup. The 20 cm tube differs from the longer XK 50/30 tube and should not be substituted without verifying the complete column configuration and required bed height. Replace the tube if damage could affect containment or the mechanical integrity of the assembly. When installing the replacement, protect the glass edges, seat all column seals correctly and follow approved column assembly and pressure-check procedures. This item supplies only the inner glass column tube; it is neither the external acrylic temperature-control jacket nor a complete ready-to-pack column with accessories.
