Third-party peptide testing for vendors

Why independence matters

Florida Chemical does not sell peptides. We test them. That separation is the reason our COAs are defensible: the lab issuing the certificate has no commercial interest in the outcome. For a research peptide vendor, that independence is the difference between "we tested it ourselves" and "an accredited third-party tested it, and here is the public record."

What every peptide vendor COA should include

• Identity by LC-MS — confirms the observed mass matches the expected peptide.
• Purity by HPLC-UV — quantifies the percent of the sample that is the intended peptide.
• Accession number — unique per submission, verifiable in the public COA database.
• Lot number — ties the certificate to the exact batch of material.
• Analyst and reviewer signatures — required under an ISO/IEC 17025 quality system.

See our step-by-step guide to reading a COA for a full breakdown, or the HPLC-UV vs LC-MS methods page for how each result is produced.

Public COA database

Every certificate we issue for a vendor is published to our public COA lookup. Your customers can search by accession number, your company name, the product or the lot — and download the signed PDF directly. That single link is often more persuasive than any marketing page.

Getting started as a vendor

1. Email Sales@Floridachemco.com with the peptides you plan to submit, expected volumes and cadence.
2. We agree the test methods — peptide purity by HPLC-UV is a flat $199.00 per sample; LC-MS identity, content/assay and extended tests are quoted separately.
3. Ship samples with your lot numbers. We issue an accession number on receipt.
4. Results are reviewed, signed and published to the public COA database in 24–48 hours from receipt, and the signed PDF is delivered to you.
