Lot lookup
Verify a lot.
Type the lot number from your vial’s label. If the lot is ours, you’ll see the record we published before it went on sale: its purity, its observed mass and its certificate.
Reading the result
What each answer means.
A lookup answers one question: is this lot in our records? If it is, you see what was recorded for it.
-
Published
On record, as published
The lot is in our published records. You see what is on file for it: HPLC purity, observed mass, test date, laboratory and the certificate itself.
-
Published · corrected
Published, then corrected
A published value was corrected. Every change is listed under the record, with its date and the reason given.
-
Published · not on saleNot on sale · corrected
On record, not on sale
It no longer meets today’s release rules, so it isn’t sold. Its record stays, so vials from it still verify. If it was corrected, the badge says so and every change is listed.
-
RetiredRetired · corrected
Retired, still on record
A lot that has stopped shipping. Published lots are retired, never deleted, so a vial we have shipped always verifies. If it was corrected, the badge says so and every change is listed.
-
Pending
On record, not yet published
Part of its record (results, certificate, test date or laboratory) isn’t published yet, so it isn’t on sale. The record fills in as each part is.
-
Sample
A sample record, not a test
Numbers that start DS-SPEC- are sample records for previewing the site. They hold no test results, and the live store can’t sell them.
-
No match
Not in our records
Check the label again: O and 0, I and 1 are easy to mix up. If it still doesn’t match, we have no record of that lot, so the vial may not be ours.
