  3. ERL-4221 (3,4-Epoxycyclohexanemethyl 3,4-epoxycyclohexanecarboxylate)

    ERL-4221 (3,4-Epoxycyclohexanemethyl 3,4-epoxycyclohexanecarboxylate)

    Starting at: €72.00

    ERL-4221 is a cycloaliphatic, diepoxy functional organic compound that is a useful building block in the production of semi-hard to hard cured epoxy resins. It is incompatible with amines, acids and strong bases and will cure to form a resinous product. ERL-4221 is often used in manufacture of plastic embedding kits for electron microscopy. Learn More

  9. Uranyl Formate

    Uranyl Formate

    Starting at: €0.00

    Inquire for availability.

    Electron dense, heavy metal compounds of uranium, tungsten and molybdenum have long been utilized for "negative staining" in electron microscopy. As demand for ultra-fine structure in biomolecules has increased, new fine grain structure materials are required.
