Welcome to our Home Page
ChemKits, Inc. is proud to announce that Dr. George Brumlik's Framework Molecular Model (FMM) kits for Organic Chemistry are now under our management. His framework molecular models have remained unchanged since 1965. We expanded the product line with kits for students and instructors of High School AP Chemistry and college level General and Organic Chemistry. We also improved the kits by changing the carrying case which features a more durable, thinner, clear case with integral hinges and latches. You can see the parts inside, back pack the kit more easily and the hinges and latches keep the lid secure in transit.
The General Chemistry kit contains fewer tetrahedral clusters and Carbon (black) tubing than the Organic Chemistry kits but have more trigonal bipyramidal and octahedral clusters. The Instructor's kit has three times the parts as student kits. The AP Chemistry kit contains a limited number of parts in a resealable bag. Our kits help with Lewis Structures, molecular geometry and polarity, co-ordination compounds and their isomers, stereo-chemistry, conformational analysis and much more.
Our internet presence has improved with this website providing better customer support. There are part lists for each kit, the ability to order spare or replacement parts, a free down loadable instruction booklet and instructional videos.
We also offer to buy back our kits when you are done with them. This is not only a green idea but allows students to recoup some of their cost similar to textbooks.
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 kits use metal clusters that represent the central atoms and tubing for bonds.
Metal Clusters Prongs Angle Color Hybridization
Tetrahedral 4 109.5o silver sp3
Trigonal Bipyramid 5 90o + 120o brass sp2 and sp3d
Octahedral 6 90o 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.
