Step 02

Mass Spectrometry

Molecular weight verification confirms the compound's identity matches the declared sequence. Catches misidentified or substituted material.

Step 03

Independent Lab

Both tests are performed by accredited third-party laboratories. Janoshik, Krause Analytical, Chromate Analytics. Certificates published.

About Us

A UK peptide supplier built on verification

UK Peptide Lab is a UK-based supplier of research-grade peptides, operated by Oraxis Research Ltd and built around a simple principle: researchers should be able to verify exactly what is in the vial before they place an order. Every batch we release is analysed by independent, accredited laboratories using HPLC-UV and mass spectrometry, and the resulting Certificate of Analysis is published openly on the product page rather than held back behind a support request.

Because everything is stocked and dispatched from within the United Kingdom, orders placed before 2pm on a working day leave our facility the same afternoon by Royal Mail Tracked 24, packed discreetly and shipped from cold-chain storage held at -20°C until the moment of dispatch. That combination of published third-party testing, domestic stock, and traceable delivery is what separates a verified supplier from a reseller.

You can read the full story behind UK Peptide Lab, or see how every batch is tested and documented before it is released for sale.
