Restek

Restek makes the consumable side of chromatography: GC and LC columns, chemical reference standards and the liners, ferrules and fittings that wear out between them. The customers are testing labs working in environmental, food safety, petrochemical, forensic, clinical, toxicology and pharmaceutical analysis.

Sourcing Restek through Xingdaotai Limited

Reference standards have a shelf life and some must ship cold, so tell us the catalog number and the quantity you use per year. We search for columns, standards and inlet parts, and check expiry dates before quoting. For columns we can also suggest an equivalent phase from another manufacturer when the original is out of stock.
