Stainless Steel HPLC Columns

Are the prime instruments to separate molecule mixtures into individual components with solvents or supercritical fluids under high pressure.

Fundamentally we differentiate between analytical, semi-prep, prep, and production scale columns.

Care has to be taken with the selection of columns.  Some biomolecules have an affinity to steel and some molecules are unstable ore denature under pressure.

SS Columns are also used as extractors or chemical reactors. Often they have to survive extreme chemical conditions.  During the past 20 years, we have experimented with a wide range of surface implantation and specialized chemical resistant coatings.  If you use corrosive mobile phases please contact us for specially coated columns.

To pack columns a range of packing tools are required.  To assure even solvent distribution and particle retention frits are required.
