Where the reports live
All published reports are listed on the lab reports page, and each product page lists only the reports naming that product. A product with no report on file says so plainly rather than linking you to someone else's paperwork.
The fields, one by one
- Client
- Who the report was issued to. Only reports issued to North Valley Labs are published on this site.
- Accession # / COA number
- The lab's own reference for the sample it tested. Quote this if you ever ask the lab or us about a specific result.
- Lot
- The batch the sample was drawn from. This is the field that ties a report to your vial — see below.
- Received / Reported
- When the lab took the sample in, and when it issued the result. A gap of a few days between the two is normal.
- Product and size
- The material and the declared amount per vial, as submitted to the lab.
- Purity
- The proportion of the sample that is the stated compound, measured by HPLC. Reported to two decimal places.
- Identity
- Whether the lab confirmed the sample is the compound it was declared to be, by mass spectrometry.
- Net content
- How much material the lab actually measured in the vial, against the declared amount.
- Endotoxin
- On endotoxin reports, the result of the LAL test for bacterial endotoxin. Reported as a pass or fail against a stated threshold.
Matching a report to your vial
Your vial's label carries a lot number. Find that same lot number in the Lot column on the reports page, and that is the report covering your vial. If the lot on your label does not appear in the table, tell us — do not assume a report for a different lot applies to it.
Two kinds of report
You will see two report types in the table. A purity report states a measured purity percentage and confirms identity. An endotoxin report states a pass or fail against an endotoxin threshold and does not restate purity. A lot may have one, the other, or both — the table shows exactly what exists.
The source column
Every row carries a source label, and it is there so nothing on the page reads as more verified than it is:
- lab-original — the file as the testing laboratory issued it.
- vendor-download — obtained from a supplier's own published documentation.
- generated — a summary document restating a result rather than the laboratory's original issued report.
Where a row is marked generated, treat it as a summary and ask us for the underlying laboratory document if you need it for your records.
What a report does not tell you
A certificate describes the sample the laboratory tested, on the date it tested it. It is not a statement about how the material was stored after testing, and it is not an approval of any use. Everything here is supplied for laboratory research use only.
