Chrom-LinX® lab-scale empty chromatography column is a family of chromatography columns designed for simple operation, high-pressure resistance, and flexible adjustment. These empty chromatography columns are suitable for process development, process verification, quality testing, and preparative small-scale sample purification.
Please note that empty chromatography columns are only available for sale and after-sales support in certain regions. For further details, kindly consult with your local sales representative. Thank you for your understanding.
User-friendly design: Ergonomically design the components for easy grasping and handling.
Clear view: These empty chromatography columns are equipped with a measurement scale of a glass tube for easy prediction and reach a predefined bed height, and improve process reproducibility.
High-pressure resistance: These empty chromatography columns are compatible with common resins of different particle sizes, allowing operation up to 20 bar* (2 MPa, 290 psi) pressure.
Various sizes: Glass tubes with inner diameter (i.d.) of 10 mm, 16 mm, 26 mm, or 50 mm, and bed height of 200 mm, 400 mm, 700 mm, or 1000 mm provide a wide range of column volumes.
High flexibility: These empty chromatography columns are equipped with single/double adjustable capital for flexible expansion of column volumes.
Easy to clean: Each component is easy to assemble, remove, and clean.
Compatibility: Supplied with tubing and connectors suitable for a variety of common laboratory tomographic systems.

*The columns withstands pressures up to 7 bar (0.7 MPa, 101.5 psi) with 50 mm inner diameter.
Chrom-LinX® Lab-scale Empty Chromatography Column are available in two designs: single adjustable capital and double adjustable capital. The design of single adjustable capital mainly consists of a adjustable capital, a chromatography column tube and a fixed capital. The design of double adjustable capital replaces the fixed capital with an adjustable capital to extend the column volume (Fig 2).
Chrom-LinX® Lab-scale Empty Chromatography Column are equipped with 10 μm net ring (5 μm net ring being also optional), which are compatible with common resins of different particle sizes.

Fig 2. Components of the Chrom-LinX® Lab-scale Empty Chromatography Column
Chrom-LinX® Lab-scale Empty Chromatography Column are made of biocompatible materials with good chemical tolerance. The columns can be used in aqueous solutions and almost all the organic solvents commonly used in liquid chromatography of macromolecules. The columns intolerant of chlorinated hydrocarbons, acetone and other ketones, aliphatic esters, and phenol. The columns are not allowed to use the solution containing more than 2 M NaOH, 1 M HCl, other strong mineral acids, or 75% acetic acid.

Fig 3. Details of the Chrom-LinX® Lab-scale Empty Chromatography Column
Chrom-LinX® Lab-scale Empty Chromatography Column may be used at temperatures from 4° C to 40° C and pressures up to 20 bar (2 MPa, 290 psi) with inner diameters of 10 mm, 16 mm and 26 mm, and 7 bar (0.7 MPa, 101.5 psi) with an inner diameter of 50 mm.
Always clean the column and components with purified water before using.
When packing the column, the double top cap can be rotated, and the threaded shaft moves axially. This operation makes the resins easy to compress. If necessary, column packing can be performed using either a packing tube (Fig 4) or an extra column tube attached with a packing connector.
