Lab Standards
Research fundamentalsHow to read a Certificate of Analysis
Identity, purity, net content, endotoxin — what each line on a COA actually tells you, and where labs differ.
Why cold chain matters for lyophilized peptides
Lyophilized cakes are supplied in a stable dry state. Cold-chain transit and lot-specific COA data support research-material integrity.
Third-party testing, explained
Why we test every batch at an independent ISO 17025 lab before release — and what we do when a result doesn't pass.
Lot traceability from synthesis to bench
How the QR code on every vial maps back to a single manufactured lot and its full analytical record.
