Certificates of Analysis
Science you can
verify.
Every lot is independently tested before release, and every vial carries a lot number that traces back to its certificate. Here is how the process works — and how to request any COA.
Our testing standard
Four checks between synthesis and your bench
Step 01
Independent lab
Samples from every production lot are sent to an independent third-party laboratory — not tested in-house by the supplier who made them.
Step 02
HPLC purity
Purity is measured by high-performance liquid chromatography. A lot must meet ≥99% to be released. There is no second grade.
Step 03
Lot release
Only lots with a passing result are released for sale. Blend components are verified before blending, and the finished blend is tested again.
Step 04
Traceable vials
Every vial is labeled with its lot number. That number matches the COA that ships with your order and stays on file for your account.
Reading a COA
What every certificate shows.
Each certificate is specific to one lot. If a vial’s lot number doesn’t match the certificate you were given, contact us before use.
- IdentityCompound name and lot number, matching the vial label.
- LaboratoryThe independent lab that performed the analysis, and the test date.
- Method & resultTest method (HPLC) and the measured purity for the lot.
