  • At least 95% of products ship with 12 months or more of shelf life.

A certificate of analysis for every ampul

1Gravimetric CoARaw material information, lot numbers, purity, isomer ratios and calculated concentrations; CRMs include measurement uncertainty.
2Chromatographic CoAEverything in the Gravimetric CoA, plus a chromatogram confirming the mixture composition with every peak identified.
3Chromatographic Plus CoAEverything in the Chromatographic CoA, plus triplicate analysis statistically compared with a second lot; full data package available.

Look up the lot CoA with a QR code

Custom standards & standing orders

Need a formulation that isn’t in the catalogue? Restek chemists make it to order – more than 200 new formulations every month, and over a third of the ampuls shipped are custom. For custom standards, a standing order lets you draw from one large lot instead of paying full set-up costs on every small order, with less lot-to-lot variation and less waiting for production.

Which standard does your method need?

Send us the standard name, catalogue number or method you run – Tam Hung Long will recommend the right item and quote quickly.
