Browse Certificates of Analysis. Every batch independently tested for purity, identity, and endotoxins.
Have a vial in hand? Match the batch reference on your label to find that batch's COA. Don't see your batch? Email support@orvantalabs.com and we'll send it directly.
Every batch we ship is independently tested by an independent third-party laboratory for purity, identity, and endotoxin levels. We do not reuse Certificates of Analysis from upstream suppliers. We do not ship batches that fail testing. There are no exceptions.
High-performance liquid chromatography measures the percentage of the intended compound versus impurities. Our minimum threshold for shipment is 98% purity. Most batches test higher; any batch below 98% is destroyed.
Mass spectrometry confirms the molecular weight of the compound matches the expected structure. This catches mislabeled or substituted material — a known problem in the broader research-peptide market.
Limulus amebocyte lysate testing measures bacterial endotoxin contamination. We require all batches to fall below standard research-use thresholds for endotoxin levels.
