Certificates of analysis

Every compound we sell, with the certificate we hold for it: the purity the laboratory measured, the lot, the testing laboratory it names, who supplied it where that was not the laboratory, and the date. Compounds without a certificate say so. How our testing works

14 OF 21 PRODUCTS HAVE A CERTIFICATE ON FILE

“On request” means the laboratory's findings are published here but the document itself is supplied by email, because it names a compound this catalogue does not. Purity is as measured on that certificate's lot. All products are for laboratory research use only.
