We are proud to announce that the classic George Brumlik Framework Molecular Model (FMM) 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 integral hinges and latches.  You can now see the parts inside, back pack it more easily and the hinges and latches keep the lid secure and the parts organized.



     In addition to the student kit for Organic Chemistry we have added new kits for General Chemistry, Mini-Kits for AP Chemistry (not pictured) and Instructor kits for both General and Organic Chemistry.  The General Chemistry kit 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 for all three of these new kits so they are ready to use when opened.  The kit will help with Lewis structures, molecular geometry, co-ordination compounds and their isomers.  During the third quarter of 2010 we hope to introduce a kit for Crystal Lattice studies.

  Improving our internet presence will be an ongoing initiative.  We will provide better customer support than ever before.  Our website provides part lists, the ability to order spare or replacement parts, a down loadable instruction booklet and instructional videos.   

  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.
