This is ChemKits, Inc. Framework molecular model kit for instructors and students of Organic Chemistry. We acquired EduModel, Inc. Who made the original Framework Molecular Models invented by Dr. George Brumlik since the 1960s this past year. We modernized the kit with a slimmer, clear, more impact resistant case that has mechanical latches and integral hinges to keep it closed in transit. We added Instructor’s kits like this one to the product line. Our kits do not require tools to assemble/disassemble and are quiet enough for classroom or testing environments. Visit our “chemkits” website for more information, photos, demonstration videos and a free down loadable instruction booklet. This kit is similar to our Organic Chemistry kit for students, except that it has over THREE times as many parts AND most of the tubing is pre cut for plug and play model assembly. The kits consist of durable metal clusters representing atoms and colored tubing representing the bonds. Using the tubing and clusters the atoms are interconnected to construct three dimensional framework models of molecules and ions. The scale is one inch per Angstrom. The metal clusters included allow for sp, sp2 and sp3 hybridized atoms providing the ability to build single, double and triple bonds. Pi bonds is one of the strengths of these models because they accurately differentiate between sigma and pi bonds and the lack of rotation about that bond axis. They are ideal for explaining structural isomers E and Z or cis and trans, stereoisomers R and S and conformational analysis of cyclic hydrocarbons, Lewis structures, molecular geometry and organometallic co-ordination complexes. There are enough pieces included to build numerous cyclic rings such as steroids and a multitude of tubing that are color coded for Carbon, Chlorine, Bromine, Iodine, Fluorine, Nitrogen, Oxygen and others. The kits are compact enough to carry easily. Assembled models are light weight and stay assembled. We have prepared lab exercises teachers could incorporate directly into their classes.
