For courses in Chemistry. In 1965, George Brumlik developed the first molecular model set, Framework Molecular Models, for the sophomore student of Organic Chemistry. It proved to be the model set of choice for thousands of professors over a span of twenty-five years, and still remains popular. Now, with the introduction of the Universal Molecular Models, Dr. Brumlik has developed a sophomore-level set that once again is a first. No other model on the market today demonstrates the framework of a molecule, the space filling capacity of a molecule, and molecular orbitals. In addition, the set is more scientifically accurate than anything currently available in a student price range. This scientifically accurate molecular model set demonstrates the framework of a molecule, the space-filling capacity of a molecule, and molecular orbitals. Effeciently designed and constructed, the UMM set is fully interchangeable with the FMM set and features color-coded atomic valence spheres and connectors, allowing students to represent all molecules having up to 12 atoms in their valence shells.
