The Liberty Lab difference
Built around four non-negotiables.
We exist because the research community needs purity testing it can trust — testing that doesn't share an owner, a supplier, or an interest with the compounds being tested.
Efficiency
Industry-leading turnaround. Most samples tested and reported within 3–5 business days of receipt.
Effectiveness
HPLC and mass spectrometry on calibrated, regularly-validated instruments — identity and purity confirmed.
Transparency
Every Certificate of Analysis is independently verifiable through the public lookup on this site.
Reliability
Independent, third-party — we do not manufacture, source, or sell the compounds we analyze.
How it works
Simple, transparent, traceable.
