The bench · every vial drawn under its own reference
Independent testing laboratory
Certis is an independent lab. We test peptides and research chemicals against written methods, report only what we actually measure, and back every figure with a Certificate of Analysis — so a label becomes evidence, not a claim.

What we test
Every test runs on a written method and a qualified instrument. Order a single answer, or the full release picture in one pass.
The right structure and the right mass — confirmed, and told apart from look-alikes.
LC-MS · HRMSThe real compound separated from everything else, each impurity reported as a share of the whole.
RP-HPLC · UPLCHow much is actually in the vial, measured against a traceable reference.
HPLC-UVLeftover water, counter-ion and process solvents that quietly shift true content.
KARL FISCHER · GCTrace catalyst residues and heavy metals, element by element, to parts per million.
ICP-MSFor anything meant to be injectable: endotoxin and recoverable microbial growth.
LAL · CULTURE

How we test
No single reading settles a question. We confirm identity, purity and contamination with techniques that work on unrelated physics — so nothing hides behind a single measurement.
Why it’s independent
We don’t make it. We don’t sell it. We just measure it — and keep the record for seven years.
Every sample arrives under its own reference, moves through its tests with a documented chain of custody, and leaves a retained portion behind — so any result can be examined again.
Quality & data integrity →The process
Tell us the compound, the batch, and what you need to know.
We confirm the methods, the price and the turnaround in writing.
Only once it’s confirmed — labelled with your reference.
The sample runs its panel on qualified instruments.
A documented Certificate of Analysis for the batch.
Tell us the compound and what you need to establish. We’ll confirm the scope, the price and how to ship — before anything moves.
