Certificates of Analysis
Every Batch. Every Compound.
Independently Verified.
Every peptide we ship has been independently tested by an ISO 17025-accredited laboratory before a single vial leaves our facility. Purity results, endotoxin data, and identity confirmation are on file for every active SKU — and available to you.
Three Independent Tests. Every Batch, Every Time.
We do not rely on supplier data or in-house testing. Every batch is shipped to a third-party ISO 17025-accredited laboratory and must pass all three screens before release.
HPLC Purity Analysis
High-Performance Liquid Chromatography separates and quantifies every component in the sample to determine the exact percentage of target peptide. We require a minimum of 99% purity — well above the 98% industry standard. Batches below this threshold are rejected.
≥99% Purity RequiredMass Spectrometry (MS)
Electrospray ionization mass spectrometry confirms the molecular weight and amino acid sequence of each peptide. This is the definitive identity test — it is chemically impossible for the wrong compound to produce the correct spectral signature. Every batch receives a confirmed molecular fingerprint.
Identity ConfirmedLAL Endotoxin Testing
The Limulus Amebocyte Lysate (LAL) assay detects bacterial endotoxins that can invalidate cell-based research and compromise in-vitro results. Every NovaraVita peptide must clear the endotoxin threshold for research-grade materials before release — zero exceptions.
Endotoxin FreeCoA Library — All Active Peptide SKUs
Every listed compound has a CoA on file. Documents are available on request within one business day of order. Purity and endotoxin data reflect the current active batch.

17025 Lab Accreditation Standard
Transparency You Can Verify Yourself
A Certificate of Analysis is an auditable document generated by the testing laboratory — not by us. It is specific to a single production batch and carries the lab's accreditation details, testing date, methodology, and results. You can independently verify the lab's ISO 17025 accreditation through your country's national accreditation body.
- Purity percentage measured by analytical HPLC chromatography
- Molecular identity confirmed by ESI mass spectrometry
- Endotoxin level confirmed below the research-grade threshold
- Batch number cross-referenced to your order and our retained records
From Synthesis to Shipment
Every NovaraVita peptide follows a locked quality chain. No shortcuts. No self-certification. No batch ships until all four gates are cleared.
Solid-Phase Synthesis
Peptides are synthesized using FMOC solid-phase chemistry at a contracted GMP-compliant facility. Amino acid sequence is specified and verified against the target compound before production begins.
Preparative HPLC Purification
Each batch undergoes batch-scale chromatographic purification to remove truncated sequences, deletion products, and synthesis impurities. Analytical HPLC must confirm greater than 98% purity before the batch advances.
Third-Party Laboratory Testing
The purified batch is shipped to an ISO 17025-accredited independent laboratory. HPLC purity analysis, ESI mass spectrometry identity confirmation, and LAL endotoxin screening are conducted. Results are returned in writing and retained on permanent file.
Lyophilization & QC Release
Batches that pass all three tests are lyophilized (freeze-dried), sealed in sterile vials, and placed under a QC hold until the CoA is filed. Batches that fail any test are destroyed — not reworked or sold at a lower grade.
Questions About Our Testing
What is a Certificate of Analysis?
A Certificate of Analysis (CoA) is a formal document generated by an independent laboratory that reports the test results for a specific production batch of a compound. It is not a marketing document — it is a laboratory record that includes the lab's name, accreditation number, testing date, methodology, and the actual measured results for identity, purity, and any safety screens conducted. Each CoA is batch-specific: it applies to a single production run and cannot be used to represent a different batch.
Why do you use third-party laboratories instead of in-house testing?
In-house testing creates a conflict of interest: the same party that profits from selling the batch is also the party reporting its quality. By contracting ISO 17025-accredited independent laboratories, we remove that incentive entirely. The lab has no financial stake in the result — they report what they measure. You can independently verify any lab's accreditation through your country's national accreditation body (e.g. A2LA, UKAS, DAkkS) using the lab's accreditation number.
What does "endotoxin free" mean for research purposes?
Endotoxins are lipopolysaccharides shed from the outer membrane of gram-negative bacteria. Even trace amounts can trigger strong inflammatory responses in cell-based assays, confounding results and invalidating experiments — particularly in cytokine studies, immunology research, and any work involving primary cells. The LAL (Limulus Amebocyte Lysate) test quantifies endotoxin levels in EU/mL. Our peptides are tested against the threshold appropriate for research-grade materials, and no batch is released above that level. This is especially important for researchers running sensitive biological assays.
How do I get the CoA for my specific order?
Email support@novaravita.com with your order number and the specific SKU. We retain CoA documents for all shipped batches on permanent file and will provide the document within one business day. Please note that the CoA is batch-specific — if you have ordered the same compound across multiple orders, each order may reference a different batch and a different CoA.
How do you consistently achieve 99%+ purity?
After synthesis, each batch undergoes multiple rounds of preparative HPLC until analytical HPLC confirms purity at or above our 99% threshold. This process takes longer and produces smaller yields than stopping at 98% — but it is the standard we hold. Batches that cannot reach 99% after purification are not sold at a lower grade or relabeled: they are rejected. This rejection rate is the cost of the standard we maintain.
Purity You Can Verify. Results You Can Trust.
Every batch is tested. Every CoA is on file. Every compound is traceable from synthesis to shipment. Start your protocol knowing exactly what you're working with.
