PerformanceLabsUK supplies third party tested research reference materials for in vitro laboratory and scientific research use only, not for human or veterinary use.
Independent lab testing is the backbone of any credible research reference material. This article explains, in plain terms, how third-party testing works and what a resulting Certificate of Analysis actually tells a buyer.
A representative sample is drawn from a manufactured batch and sent to an independent laboratory. The laboratory applies its chosen analytical method to assess identity and purity, then issues a report. That report, once matched to its batch number and published by the supplier, becomes the Certificate of Analysis a buyer can review.
| Approach | What It Confirms | Limitation |
|---|---|---|
| In-house testing only | Supplier's own quality control | No independent verification |
| Independent third-party testing | Batch identity and purity confirmed externally | Confirms composition only, not safety or sterility for human use |
| Published Certificate of Analysis | Traceable result tied to a specific batch | Only useful if the batch number matches the product received |
PerformanceLabsUK has every batch of its research reference materials independently tested by Janoshik Analytical. The batch-specific Certificate of Analysis is available on request, and sample Certificates of Analysis will be published in the COA Library as they become available. This reflects the same principles described above, applied to its own catalogue.
