Quality you can cite.
Every batch is analysed by an independent UK laboratory before release. HPLC purity, mass spectrometry identity, and a signed Certificate of Analysis in every box.
HPLC & MS
High-performance liquid chromatography and mass spectrometry confirm identity and purity.
Certificates of Analysis
A CoA travels with every batch so you can reference it in your research records.
Controlled synthesis
Lyophilized and sealed under controlled laboratory conditions to protect integrity.
Insulated shipping
Temperature-stable packaging with tracked UK & EU delivery and shipment protection.
Documented from vial to bench.
- Batch samplingA representative sample from each production lot is pulled for QC before release.
- HPLC purityReverse-phase HPLC at 220 nm quantifies purity against our ≥99% target.
- Mass spectrometryMS confirms molecular weight and peptide identity match the reference sequence.
- Cold-chain packingLyophilised, sealed, insulated and shipped with tracking — signed CoA included.
Our commitment
We partner with independent laboratories and document every batch before it reaches your research facility. Our quality workflow is designed for labs that require reproducible results and transparent chain-of-custody documentation. If you need a specific CoA, testing method, or batch record, our team will provide the documentation available for your product.
