Test Reports
Every lot that leaves our facility is characterized by an independent, third-party laboratory. The certificate of analysis is the paper trail behind that work — a per-batch record you can pull before any material touches your bench. For research use only.
What we test for
Four checks define whether a batch is release-ready. Identity is confirmed two ways, purity is held to a hard floor, and supporting panels document the rest.
HPLC Identity
Reverse-phase high-performance liquid chromatography resolves each compound against a reference standard, confirming identity and flagging related-substance impurities before a lot is released.
Mass-Spec Confirmation
Mass spectrometry verifies the measured molecular weight against the expected sequence, providing an orthogonal check that the material in the vial is what the label claims.
≥99% Purity Threshold
Lots are held to a minimum 99% chromatographic purity. Any batch that falls below the threshold is quarantined and does not reach inventory.
Endotoxin, Sterility & pH
Supporting panels — endotoxin load, sterility screening, and reconstitution pH — round out the profile so each lot is characterized beyond identity alone.
Sample lab reports
A selection of current lots and the reports that accompany them. Each Certificate of Analysis is tied to a specific batch identifier so results always trace back to the exact material in hand.
