Every lot is assayed by an independent laboratory before it reaches the catalog — purity by reverse-phase HPLC, identity by mass spectrometry, and a unique lot ID linked to its certificate.
Follow the line. Each checkpoint is documented, independently verified, and shipped with your order.
Every lot is independently assayed at an outside laboratory.
Reverse-phase HPLC for purity, mass spectrometry for identity — run by a lab with no stake in the result. We don't grade our own work.
The measured purity figure is recorded before a compound is listed.
That figure is printed on the certificate tied to that exact lot. No number is published without a result behind it.
Lot-traceable paperwork for the exact vial in your hand.
Pull the certificate for any lot, any time, from the COA database — filed against the lot ID printed on the vial.
Four steps, in this order, every time. Skipping one isn't an option we've given ourselves.
We choose manufacturing partners who document identity and purity before a lot ever leaves them. We know where every batch starts.
Every lot is re-tested at an independent laboratory — two sets of eyes on the same batch is how we keep control honest.
The certificate goes live against the lot number before the vial is listed. You can look it up before you buy.
Held in temperature-controlled storage at our US facility until your order is placed, then packed and dispatched — usually the next business day.
Results are attached to the specific lot record and retrievable from the COA database — never averaged across a product line.
We do not publish template documents, generalized purity percentages, or product-level aggregate values.
Pure Helix makes none of those claims for any material we distribute. Compounds are supplied for in-vitro laboratory research only.
Conditions appropriate for lyophilized research reagents, with temperature-controlled packaging where indicated.
Every vial third-party tested, lot-traceable, and shipped with its certificate.
