Look up a lot number
The lot number is printed on the vial label. Type it in and you get the release record as the laboratory returned it: purity, identity, water content, endotoxin and the date it cleared.
What gets tested
Purity by RP-HPLC at 214 nm, identity by UPLC-MS, residual water by Karl Fischer and bacterial endotoxin by LAL.
Who runs it
An outside laboratory, on a sealed sample drawn from the finished lot. Our own bench data never releases a lot on its own.
How long we keep it
The signed certificate ships with the order and stays on the product page for as long as the lot exists. We also keep a retention sample.
