About PureLab Peptides
PureLab Peptides exists to support the academic and independent research community with peptide reagents whose composition, purity, and handling can be independently verified. We publish a Certificate of Analysis for every batch we ship, store inventory under cold-chain conditions, and dispatch from the United Kingdom — because reproducible research begins with reagents you can trust.
Analytical Rigor
Every batch tested by HPLC-UV against documented specifications.
Independent Verification
Third-party CoAs from Janoshik Analytical — never in-house only.
Cold Chain Integrity
Continuous -20°C storage with chilled-pack dispatch.
Our Testing Process
- 1
Sourcing from cGMP-certified synthesis partners
We work only with synthesis facilities operating under current Good Manufacturing Practice with documented quality systems.
- 2
Independent third-party purity testing (HPLC)
Every incoming batch is submitted to Janoshik Analytical for reverse-phase HPLC analysis — no batch is sold without an external CoA.
- 3
ICP-MS heavy metal screening
Trace metals are screened by inductively coupled plasma mass spectrometry at ppm sensitivity.
- 4
Cold storage from receipt to dispatch
Lyophilised peptides are held at -20°C from receipt to shipment, with chilled handling on dispatch.
- 5
Batch documentation published before sale
Each CoA is uploaded to our public Testing Archive before the batch is listed for purchase.
