The 160 mm column is a plain column with an integral reservoir.

It is tapered to a 2 mm bore capillary tip and has a top tooled for a #2 rubber stopper. The 200 mm columns are general purpose columns for quick separations. Their funnel-shaped tops permit easy filling and hold additional solvent. The 250, 300 and 400 mm columns are basic columns used for many separations in adsorption and ion exchange chromatography.
