We are proud to announce that the classic George Brumlik Framework Molecular Model (FFM) kits for Organic Chemistry shown above introduced in 1965 are now under our management. The first kit to use the term Framework Molecular Models has remained the same since it's inception. We have modernized the kit and expanded the product line with kits for other Chemistry courses.  The kit's new features include a thinner clear case with hinges and mechanical latches.  You can now see the parts inside, it is back packed more easily and the hinges and latches keep the lid secure and the parts organized.

   We now offer a smaller kit intended for General Chemistry.  It  contains fewer tetrahedral clusters and Carbon (black) tubing than the Organic Chemistry kit but has more trigonal bipyramidal and octahedral clusters.  The parts are pre-cut so the kit will be ready to use when opened.  The kit will help with Lewis structures, molecular geometry, co-ordination compounds and their isomers.  During the first quarter of 2010 we will introduce a kit for Crystal Lattice studies, larger kits for Instructors, Mini-Kits suitable for high school AP Chemistry classes and lastly, pre-built models for display.  The pre-built molecules will be mounted handsomely for office display.

  Improving our internet presence will be an ongoing initiative.  We will provide greater customer support than ever before.  We are providing parts lists and you can order spare or replacement parts in our store.  We have pictures and videos on Youtube.com to demonstrate the various uses of our kits.  The original instruction booklet in an easy to download pdf format and the same videos will be added to this site very soon.  

  We are announcing something no other kit manufacturer is doing.  We are offering to buy back our kits.  This is not only a green idea but allows students to recoup some of their cost just like they do now for textbooks without the hassles of posting and selling their kit online.

    We are excited about our new venture and hope you will explore the possibilities of improved learning with the use of our kits.

Product Description

    Our FMM kits use metal clusters that represent the central atoms.  The bond angles are accurate for standard molecules.

Metal Clusters         Prongs      Angle         Color       Hybridization

Tetrahedral                   4           109.5^o         silver          sp³
Trigonal Bipyramidal       5         90^o + 120^o     brass         sp² and sp³d
Octahedral                    6             90^o            copper        sp  and sp³d²


  Bonds are represented by colored plastic tubing cut to length (1 inch = 1 Angstrom) for the desired bond.  The tubing easily slides on and off the metal prongs and fit snug enough to stay in place while examining the model.  The kit also includes two-color tubing to provide pre-assembled versions of the most common bonds.
