Batch lookup
Verify the vial in your hand.
Enter the batch or lot number printed on the label. We return the verification record we hold — never the vendor's claim.
Where to find the number
The lot or batch number is printed on the vial's label, usually alongside the manufacture or test date — not the product name.
What we return
The testing laboratory, HPLC purity, mass spectrometry identity status, and test date — read directly from the certificate of analysis a human reviewed before publishing.
If it is not on record
A missing record doesn't by itself mean the batch is illegitimate — it means no vendor has published this lot to VialCheck, or it hasn't been reviewed yet.
