Quality & CoA
How every batch is verified
Research depends on knowing exactly what is in the vial. Every lot we supply follows the same documented release process, and the analytical results travel with the product.
1. Synthesis and lot traceability
Peptides are produced by solid-phase peptide synthesis under controlled conditions. Each production run receives a unique lot number that is printed on the packaging and recorded against your order.
2. Independent analysis
Before release, samples from every lot are sent to an independent accredited laboratory. High-performance liquid chromatography (HPLC) establishes purity, and mass spectrometry (MS) confirms molecular identity against the expected mass.
Lots must meet our ≥99% purity specification. Anything below specification is rejected and never offered for sale.
3. Certificates of analysis
The certificate of analysis (CoA) for the current lot is published on each product page where available, and can always be requested by email quoting your order reference.
4. Packaging and cold chain
Vials are sealed with aluminium crimp caps; pre-filled research pens are factory sealed. Orders ship in insulated, temperature-controlled packaging with tamper-evident seals, and every parcel is tracked.
On arrival, store products refrigerated at 2–8°C, protected from light. Do not freeze.
