C columns are economical empty columns suitable for low pressure liquid chromatography and gravity feed at the lower volumes used at research scale.

• Economical – for low pressure liquid chromatography at research scale
• Broad compatibility – functions with a stand-alone pump, chromatography system, or gravity feed
• Precise temperature control – with the optional cooling jacket
• Efficient packing – packing reservoirs are available as accessories specific to each column diameter

Standard C-series columns have a fixed volume, but they can be upgraded through the addition of flow adapters. These work to keep bed height constant and protected from insoluble particles during chromatography. Adjustable flow adapters are available for 10 mm (AC 10), 16 mm (AC 16), and 26 mm (AC 26) diameter C columns.

Three RC packing reservoirs help optimize packing conditions, especially when packing high beds. They are available for each diameter in the C column series, and are quick and easy to assemble. After the resin is in the column, the RC reservoir can be connected to a pump or Mariotte flask to give optimal flow rates for packing.

Resolution and recovery can often be increased by fitting C columns with a JC thermostatic jacket during temperature-dependent low-pressure chromatography. JC jackets increase control of separation temperature and mechanical resistance of these columns, enabling operating pressures of up to 1 bar.
