Strict Quality Control & Global Cold Chain Logistics Protection

1. Full Closed Aseptic Production Flow

   
   

   Raw material synthesis, multi-stage purification, recrystallization and split packaging are all completed in isolated Class 10000 dust-free aseptic workshops, with real-time monitoring of air cleanliness, temperature and microbial indicators throughout the whole production process. No heavy metal pollutants, exogenous bacteria or endotoxin impurities will be introduced into finished crystalline powder.
2. Multi-Item Mandatory Batch Inspection Before Shipment

   
   

   Every finished production batch will complete three mandatory inspection procedures before delivery: visual powder appearance inspection, HPLC quantitative purity detection, and endotoxin content quantitative testing. Any batch failing any inspection standard will be fully discarded and will not be delivered to global customers to avoid disrupting laboratory research progress.
3. Constant Low-Temperature Cold Chain Transport Protection

   
   

   All sealed product packages are placed in insulated foam cold storage boxes filled with phase-change ice packs. The insulated box can maintain stable 2~8℃ low-temperature environment for more than 96 hours during cross-border air and sea transportation, fully protecting the biochemical activity of Melatonine crystalline powder during long-distance international logistics.
4. Flexible Customized Service For Research Clients

   
   

   We provide adjustable compound dosage, customized packaging weight and confidential neutral packaging services according to customers’ specific experimental requirements. For bulk orders over 100 vials, exclusive customized batch testing standards and personalized English certification documents matching university and research institute filing standards can be provided.
