We have been in business since 1996 and are a premier manufacturer and global supplier of stable isotopes and select radioisotopes for science, medicine and industry. We ship worldwide. Assuming we have your isotope in inventory, we can arrange same-day shipment. ISOFLEX USA also supplies a number of specialty isotopes including Depleted Zinc (DZO/DZA), Lithium-7 and Helium-3. Our subsidiary, ISOFLEX Radioactive LLC (ISO-RAD), specializes in radioactive sources including Iridium-192 and others. ISOFLEX USA offers a broad line of research, medical and industrial isotopes including Fe-57, Te-124, Ni-64, Zn-68, Ge-76, Ca-48, Mo-100, Mo-98, and hundreds of others. Normally, we do not supply the lighter isotopes such as Deuterium (2H), Carbon-13 and Nitrogen-15, but we welcome your inquiries. More recently, IUSA broadened its product offering to include a product line supporting the nuclear medicine industry. Our NUCMEDCOR division offers O-18 Water and PET consumables for synthesis modules (GE, Siemens, IBA), such as cassettes, purification columns and reagent kits, PET chemicals such as Mannose Triflate and Cryptand 222, as well as custom synthesis and other accessories including sterile vials and sterile vacuum vials.
