Questions
What the code on the label proves, what the batch number means, and how the vials are meant to be stored.
Verifying a vial
How do I check that a vial is genuine?
Scan the QR code on the label with your phone camera. It opens a page that tells you whether that exact unit is in our database, which batch it belongs to, and how many times it has been read.
Can I type the code instead of scanning it?
No, and that is deliberate. A code that can be typed can be tried, shared and guessed at. It is only valid when read directly from the label.
The page says the vial was already read before. Is it fake?
The first reading of a code should be yours. Nobody handles a vial between this laboratory and you, so a code that has already been read before your first scan means something happened on the way. Take it up with whoever sold it to you, batch number in hand. Scanning the same vial again yourself is normal and counts normally.
Why does each vial have its own code instead of one code per batch?
A batch code tells you which run a vial came from, and anyone copying a label copies that code along with everything else. A code unique to the unit does not survive being copied: the moment two people scan the same code, the count says so.
Can someone read my code out of your database?
No. We store a one-way hash of each code, never the code itself. Verification works by hashing what was scanned and looking for a match. Even with full access to the database there is no code to read back out, and that holds for us as much as for anyone else.
The QR code will not scan.
Clean the label, move to even light and hold the camera about a hand away. If the printed square is damaged or missing, do not treat the vial as verified: an unreadable code proves nothing either way.
The product and the label
What does the batch number tell me?
It identifies the production run, together with the manufacturing and expiry dates printed next to it. It is how a specific vial is traced back to how and when it was made.
How should the vials be stored?
Store the vials at 2-8 °C. Do not freeze. Each product page carries its own storage line.
Do you sell through this website?
No. This site presents our portfolio and a verification tool. There are no prices and no checkout here.
What does the expiry date on the label refer to?
The unopened vial as it was manufactured, stored under the conditions on the label. It is printed next to the manufacturing date so both are visible at once.
What does "≥99% by HPLC" mean?
At least 99% purity, measured by high-performance liquid chromatography. It is the figure printed on the label.
What is this material supplied for?
Laboratory research. Everything in this portfolio is supplied for research use only.
Holding a vial right now?
Scan the code on its label. It tells you whether that exact unit left this laboratory.
