Analytical Testing

High-Performance Liquid Chromatography

HPLC separates each compound into its constituent components, producing a chromatogram that reveals exact purity percentages. A single sharp peak at the correct retention time confirms identity and purity above 99%.

Reversed-Phase HPLC
C18 column separation with UV detection at 220nm for precise purity quantification
Mass Spectrometry (LC-MS)
Molecular weight confirmation via electrospray ionization to verify compound identity
Endotoxin Testing (LAL)
Limulus Amebocyte Lysate assay ensures sub-threshold endotoxin levels for research safety
Purity Standards

Beyond Industry Benchmarks

Where most suppliers target 95% purity, BeaCapra holds every batch to 99%+ with independent verification and full transparency.

99%+ Guaranteed
Every peptide ships with independently verified purity at or above 99%. Batches below threshold are rejected — no exceptions.
Third-Party Labs
All testing conducted by independent, ISO 17025-accredited laboratories. We never self-certify — every COA bears an external lab signature.
Batch Traceability
Every vial carries a lot number that maps to its complete testing history. Scan or enter the code on our site to view the original COA.
Quality Pipeline

From Raw Material to Your Lab

Six checkpoints ensure every compound meets pharmaceutical-grade standards before it ships.

01
Raw Material Audit
Amino acids and reagents sourced from qualified, GMP-certified suppliers with incoming QC checks
02
Solid-Phase Synthesis
Fmoc SPPS on automated synthesizers with real-time coupling efficiency monitoring
03
Purification
Preparative HPLC removes truncated sequences and side products to isolate the target peptide
04
Analytical QC
HPLC purity, LC-MS identity, endotoxin, and sterility testing by third-party labs
05
Lyophilization
Freeze-dried under controlled vacuum for long-term stability, then sealed in sterile vials
06
Cold-Chain Shipping
Insulated packaging with temperature indicators ensures product integrity from warehouse to doorstep
