Spectra/Chrom® Chromatography Columns

Spectrum Chromatography is the premier supplier of low-pressure liquid chromatography columns to biochemical researchers. The available columns range in length from 10 to 200 cm (about 4 inches to 6 feet) and in diameter from 0.6 to 15 cm (about 1/4 to 6 inches). The column bodies are borosilicate glass (generally Pyrex®) and the endplates are made of various plastics.

Our columns are put into two categories which reflect their intended applications and materials of construction:

Aqueous Series Columns


Our aqueous series columns feature black polypropylene endplates. These are resistance to dilute organics and to reasonably concentrated (2 N) acids and bases. These columns each include two fixed (stationary) endplates; the lower endplate includes a 10 µm bed support and the upper endplate includes a vent port for venting any gas which may accumulate in the column. Accessories which can enhance the utility of these columns include adjustable plungers (a.k.a. flow adapters) for adjusting the packed length of the column and water jackets for controlling the temperature of the columns.

Organic Series Columns


Our organic series columns feature inert white polytetrafluoroethylene (PTFE) endplates, the only wetted materials in these columns are glass and inert PTFE. These are resistance to most chromatography solvents, including acids and bases. These columns each include two fixed (stationary) endplates; the lower endplate includes a 10 µm bed support and the upper endplate includes a vent port for venting any gas which may accumulate in the column. Accessories which can enhance the utility of these columns include adjustable plungers (a.k.a. flow adapters) for adjusting the packed length of the column and water jackets for controlling the temperature of the columns.
