IS now offers a larger variety of tubing for your Chromatography and Laboratory needs. Please note that burst pressures, where
listed, should be regarded as absolute limits. Your routine operating pressures should include a suitable safety margin based
on your specific application and equipment.
Copper Tubing
Flexible 1/8" copper is a convenient, non-permeable means of supplying GC carrier gas, Helium for sparging HPLC reservoirs,
detector gas supplies, etc. Bulk copper tubing should be solvent-cleaned before use to assure that it is free of contamination. Rinse the
tubing with Methanol and Methylene Chloride, then connect it to a clean gas supply and heat the tubing to remove residual solvent.
Stainless Steel Tubing - Chromatography grade - 316
Stainless steel is the most common material for most routine HPLC applications. Its high strength (burst pressure
>8000 psi), general inertness and resistance to corrosion make it the standard material for HPLC plumbing. Stainless
steel can corrode under extremes of pH, and it can bind proteins as well as contribute metal ions to mobile phas-
es. These properties make stainless steel incompatible with the analysis of many biomolecules and the use
of buffers with high ionic strength. Bulk stainless steel tubing from SIS is solvent-cleaned and baked prior
to shipment.
316 Stainless Steel Pre-cut Tubing
These pieces are cut with an electronic discharge method which leaves the ends perfectly flat, open, and burr-free. Precut stainless
tubing is passivated, cleaned and rinsed.
