*The columns withstands pressures up to 7 bar (0.7 MPa, 101.5 psi) with 50 mm inner diameter.

Product Characteristics of Chrom-LinX Laboratory Grade Empty Columns

Chrom-LinX® laboratory grade empty chromatography columns are divided into two designs: single adjustable capital and double adjustable capital. The design of single adjustable capital mainly consists of an 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® laboratory grade empty chromatography columns is standard equipped with 10 μm net ring (5 μm net ring being also optional), which is compatible with common resins of different particle sizes.

Chemical Resistance of Chrom-LinX Laboratory Grade Empty Columns

Chrom-LinX® laboratory grade empty chromatography columns 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.

Instructions of Chrom-LinX® Empty Chromatography Column

Chrom-LinX® laboratory grade empty chromatography columns 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.
