How do I look up my BT BioLabs COA by batch number?
Enter your batch number on the COA Lookup page to retrieve your Certificate of Analysis. Each batch is linked to its HPLC chromatogram, mass spectrometry data, and purity documentation. Batch numbers are provided with your peptide order documentation.
What information is included in a BT BioLabs Certificate of Analysis?
Each COA includes: batch/lot number, product name and CAS number, HPLC purity percentage with chromatogram, mass spectrometry (MS) molecular weight confirmation, net peptide content, appearance and solubility data, and testing date. Documentation is provided for Research Grade lyophilized peptides.
Can I verify peptide purity from the COA report?
Yes. The HPLC chromatogram on your COA shows the purity profile with retention time and peak area percentage. Cross-reference the reported purity value with the chromatogram to verify consistency. Mass spectrometry data confirms the correct molecular weight for your peptide.
How long does COA verification take?
COA lookup is instant for documented batches. Simply enter your batch number on the COA Lookup page to access your documentation. If your batch is not found online, contact our Quality team at info@btbiolabs.com with your order reference for manual verification support.
What is HPLC purity and why does it matter for peptide quality?
HPLC (High-Performance Liquid Chromatography) purity measures the percentage of target peptide relative to impurities in a sample. For research-grade peptides, \u226595% purity is standard; BT BioLabs typically delivers \u226598% purity. Higher HPLC purity means more reliable research results, fewer confounding variables, and better batch-to-batch consistency for your quality control workflow.
What should I do if the COA does not match my product?
If the Certificate of Analysis shows a different batch number or peptide identity than your received product, do not use the material. Contact BT BioLabs immediately via WhatsApp or the contact form with photos of the product label and the mismatched COA. Our quality team will investigate and provide the correct documentation or arrange a replacement \u2014 typically within 24 hours.
