Quality & testing
Certificate archive
Certificates of analysis, indexed by lot number and published as batches are released. Certificates are hosted on this site under their lot number, so a record stays available after its batch sells through.
Certificates are published here as batches are released. Each entry will list the batch’s lot number, compound, date tested, analytical method, and testing laboratory, with the certificate itself available to download.

What a certificate actually records
A test result, the method that produced it, the date and the lot. Because it is issued for one lot, a certificate for one batch is not evidence about another, and laboratory accreditation covers a defined scope of methods rather than everything a laboratory can measure.
Cross-checking

Read the lot number off the vial
The lot number printed on the vial label identifies the batch it came from. The archive matches on that number exactly as printed.

Look it up in the archive
The archive lists one entry per batch: the same lot, the same certificate, for every vial filled from it.

Compare the certificate to the vial
The compound name and lot number on the certificate should match the vial label. If a lot doesn’t appear in the archive, contact us with the lot number and we’ll trace the batch record.
