1. Cold-Chain & Chemical Stability Restrictions
Due to the temperature-sensitive nature of lyophilized peptide cakes and strict quality control standards, physical returns of opened or non-defective chemical products cannot be accepted for re-stocking. This policy ensures every researcher receives factory-fresh compounds stored under unbroken nitrogen blanket protocols.
2. Damaged in Transit Guarantee
If vials arrive physically fractured, compromised, or with broken crimp seals, notify our laboratory dispatch desk within 72 hours of delivery with photographic documentation. A replacement lot will be dispatched immediately via expedited priority courier at zero cost.
3. Analytical Purity Guarantee
If independent third-party analytical testing (RP-HPLC or MS) performed within 30 days of receipt reveals purity below the specification printed on your Certificate of Analysis, we will issue an immediate lot replacement or full scientific refund.
