OpenLaboratory storage guidance
Full reference: Laboratory storage of research materials. Lyophilized materials are typically held at −20°C, protected from light and moisture. Solution preparation follows institutional laboratory SOPs — not human-use instructions.
Understanding a COA
For a full educational article, read Understanding Certificates of Analysis.
- Lot number — unique batch id on the vial; opens the Research Vault.
- Identity — analytical evidence consistent with the expected compound (commonly mass spectrometry).
- Purity — chromatographic purity for the released lot (commonly HPLC).
- Test / release dates — when the lot was analyzed and released for distribution.
Frequently asked
What is the Research Vault?+
A dedicated page per batch with certificate summary, laboratory results, purity, identity, lot history, and a QR target for vial labels. Live COA PDFs attach when supplier lots are received.
What documentation ships with an order?+
Eligible lots link to batch-specific documentation covering identity, purity, and test date via the Research Vault and packaging COA insert when available.
Who can create an account?+
Accounts are limited to users who confirm they are at least 21 years old and agree that purchases are for laboratory research use only.
How is purity determined?+
Purity is typically assessed by HPLC and identity by mass spectrometry through testing laboratories, documented per lot when results are available.
How should materials be stored?+
Store lyophilized material at −20°C unless a product page specifies otherwise. Protect from light and moisture. Solution preparation must follow institutional laboratory SOPs.
