Spectra/Chrom® Aqueous Chromatography Columns

Spectrum Chromatography manufactures a complete line of low-pressure chromatography columns. The two most popular series are the standard aqueous columns described here and the organic series. Replacement parts for these columns are readily available in the event of damage, as are a variety of accessories.

Also available are a variety of inexpensive disposable plastic columns.

Each column comes with a 10 micron bed support making them suitable for use with most low pressure media. Each column also includes tubing fittings, making them ready to use. The fittings on the 0.6, 0.9, 1.5 and 2.5 cm diameter columns are for use with 3/16" OD tubing; the fittings on the 7.5, 10, and 15 cm diameter columns are for use with 1/4" OD tubing. The 100, 120, and 150 cm long 5 cm diameter columns come with 1/4" fittings while the shorter 5 cm diameter columns come with 3/16" fittings.

The aqueous columns listed here are intended for use with aqueous solvents. The wetted materials in these columns are PTFE, polypropylene, borosilicate glass, and nitrile rubber. These are suitable for use with most aqueous solutions including most acids, bases, and salts. If your application requires additional solvent resistance please see our organic columns.
