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.

Cross-checking

Match a vial to its certificate

  1. 1

    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.

  2. 2

    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.

  3. 3

    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.
