How material reaches this catalog.
Lot discipline
Every vial carries a lot number, and every order records the lot or lots that shipped. Every lot will be submitted to an independent analytical laboratory and tested for identity, purity (%) and quantity per vial (mg). Each lot's certificate will be published by lot number.
Testing panel
Every lot will be submitted to an independent analytical laboratory and tested for identity, purity (%) and quantity per vial (mg). Each lot's certificate will be published by lot number.
The laboratory, report number and report date for a lot are printed on its certificate.
Sourcing
Each compound is purchased from an independent supplier against a written identity and purity specification. Every lot will be submitted to an independent analytical laboratory and tested for identity, purity (%) and quantity per vial (mg). Each lot's certificate will be published by lot number. The supplier record and test result for each lot will be retained and tied to its lot number, the same number printed on the vial and referenced on its certificate.
Storage
Materials are held sealed at room temperature until dispatch. Lyophilized material ships ambient — it is stable at room temperature for the duration of standard transit.
