Our story

Every batch tested. Every certificate published.

Nothing is listed on a supplier’s word. Every batch is run on two separate methods by an independent laboratory, RP-HPLC for purity and LC-MS for identity, and reaches the catalogue only once both results agree.Independently tested, batch traceable, certificate published. That is what a batch has to be before it is listed, and the reason material gets held back rather than shipped.

Master Biolabs. Supplying UK laboratories and research businesses, dispatched from the UK and tracked to the door.

The Master Biolabs standard

Why researchers choose Master Biolabs

Everything we say about a batch is something you can check from its certificate. No figure on this site that you cannot trace back to an independent laboratory report.

Quality and testing

How a batch earns its certificate

The laboratory name, the method detail, the chromatogram, the endotoxin screen and the heavy metal screen appear in full on every certificate we publish.
