Check a certificate.
Any Certificate of Analysis we issue can be checked here against the laboratory's own records — by anyone holding it, at any time, free.

How verification works
01
Scan or type
Every certificate we issue carries a QR code that opens this page, and the same 16-character code printed beneath it for typing by hand.
02
Compare
The page shows the record as it exists in our laboratory system: sample, batch, dates and results. If anything differs from the document in front of you, trust this page — not the document.
03
Check the file
For PDFs we also publish the file's SHA-256 fingerprint. Recompute it on your copy: if even one byte was altered after issue, the fingerprints will not match.
A lookup reveals nothing beyond the certificate itself: records carry no client information, and codes cannot be browsed or guessed. If a certificate does not verify, or verifies with different results than the copy you were shown, we want to know — contact the laboratory.
