liquilabs is not currently listed as ISO/IEC 17025 accredited — the international standard for testing and calibration laboratories. This is not unusual in the peptide testing market (most listed labs lack it). Accredited results carry more regulatory weight in formal contexts. Read about lab accreditation standards →

About liquilabs

Czech-based family-owned analytical laboratory in Prague providing peptide content, purity, endotoxin, bioburden, and heavy metal testing via HPLC-UV, HPLC-MS, ICP-MS, and AAS across 6 industry sectors.

What sets liquilabs apart

  • ✓Broadest analytical method menu of any EU lab in the Peptigrity index — HPLC-UV, HPLC-MS, ICP-MS (heavy metals), AAS (atomic absorption spectroscopy), GC, UV/VIS spectroscopy, and total organic carbon analysis. Coverage spans purity, identity, contamination, and structural verification without subcontracting.
  • ✓USP-aligned compendial methods — endotoxin per USP <85> and elemental impurities per USP <232>. Methods are documented against United States Pharmacopeia chapters used in pharmaceutical-grade analysis, rare in the peptide testing market.
  • ✓Stability study capability — Liquilabs has run published accelerated stability studies on research peptides (including BPC-157 under elevated temperature and humidity conditions). Useful for vendors and researchers needing shelf-life and shipping-stability data.
  • ✓Family-owned with long operating history — direct continuity of ownership and analytical staff, unusual in the peptide testing market.
Honest disclosures
  • Accreditation — see the note above.
  • Primary scope is food supplements, cosmetics, and biotechnology — peptide testing is one segment of a broader analytical portfolio rather than a peptide-only specialization.
  • Pricing is not published on the website — quoted per submission.

Services offered

Peptide content & purity
HPLC-UV / HPLC-MS
Quantifies peptide content and purity using two-instrument approach.
Endotoxin screening
USP <85> / LAL
Bacterial endotoxin detection per USP <85>.
Elemental impurities
USP <232> / ICP-MS
Elemental impurity analysis per USP <232> compendial chapter.
Heavy metal analysis
ICP-MS / AAS
Trace metal contamination detection — useful for samples sourced from less-regulated supply chains.
Accelerated stability studies
Multi-instrument
Published stability studies on research peptides (e.g. BPC-157) — analytical depth most peptide labs cannot offer.
