The Cytiva XK 50/20 Empty Chromatography Column, 50 mm ID, 200 mm (28988952) is designed for liquid chromatography of macromolecules at low to medium pressure. It combines a high-precision borosilicate glass tube with an acrylic thermostatic jacket and supports bed volumes up to 274 mL with a maximum operating pressure of 0.3 MPa (3 bar).
Key Features
- 50 mm internal diameter with a 200 mm column length, providing the XK 50/20 configuration for preparative chromatography workflows
- Bed volumes from 0 to 274 mL, with adjustable bed heights from 0 to 14 cm using the supplied adapter
- Suitable for low to medium pressure chromatography, with a maximum operating pressure of 0.3 MPa (3 bar)
- Operating temperature range of 4°C to 40°C, supporting controlled laboratory purification procedures
- High-precision borosilicate glass construction, forming the main chromatographic tube
- Integrated acrylic thermostatic jacket, enabling temperature control using water as the cooling fluid
- QuickLock adapter adjustment, allowing rapid positioning of the adapter during packing and bed-height adjustment
- 10 µm nylon net ring support, positioned on the plunger to support the chromatography resin bed
- Capillary tubing and 1/16-inch tubing connectors supplied, with 130 cm adapter tubing and 35 cm bottom-piece tubing
- Chemically resistant wetted materials, including borosilicate glass, glass-fibre reinforced polypropylene, polyamide, acrylic plastic, fluoro-rubber and ETFE/PTFE
- Serviceable and cleanable construction, with laboratory detergents suitable for routine cleaning and enzyme detergents recommended for proteinaceous contamination
- Multiple sterilisation options, including autoclaving after removal of the thermostatic jacket, tubing and net ring, or sterilisation of the complete column with ethylene oxide
Note: Only water should be used as the cooling fluid in the thermostatic jacket. The jacket must not be exposed to pressures above 0.2 MPa (2 bar).
Benefits
- Provides flexible control of packed-bed volume and height for adapting the column to different purification requirements.
- Simplifies column packing and bed adjustment through the accessible QuickLock adapter mechanism.
- Supports temperature-sensitive separation workflows through the integrated thermostatic jacket.
- Allows direct integration with laboratory chromatography equipment using the supplied tubing and connection hardware.
- Supports routine maintenance through replaceable internal components and a design that can be disassembled for cleaning.
