What is on one
What each certificate shows
- Lab
- Named. We do not file a certificate that does not name its lab.
- Report number
- The lab's own reference number, so you can confirm the report with them.
- Purity, HPLC
- The share of the sample that is the compound, as the lab reported it.
- Identity
- Whether the compound matched the reference standard, as the lab reported it.
- Documents
- The certificate itself, and the safety data sheet for the compound.
Every row comes from the lab report. If the report does not have a field, we leave it blank rather than guess.
Why we publish
Read the result before you buy.
A supplier that says "lab tested" and shows nothing is asking you to take its word. We post the lab's report instead: which lab, their report number, the purity and the identity result.
When a compound is tested again, the newer certificate replaces the older one here and on the product page. The date on each one tells you how recent it is.
