General description

An extensive model system offering 15 atomic bonding configurations in 12 colors of plastic atoms. The carbon atom is represented in nine configurations: linear, trigonal (in five angle variations), tetrahedral, octahedral, trigonal-bipyramidal. Models come in two sizes: Orbit and Minit. Spare atom centers and bonding tubes are available for all model kits.

Please see Technical Information Bulletin AL-183 for a listing of these items, available on our website at sigma-aldrich.com
Includes all the atoms in the Orbit system and is capable of making models of organic and inorganic molecules, lattices, proteins and other tertiary structures. All four cochranes workbooks which cover basic structures, organic and inorganic chemistry, lattices and biochemistry are included in the set.
1260 atoms, 1000 bonds, 4 booklets
Premium compartmented storage boxes.
Scale: 3 cm = 0.1 nanometer (1 A), Orbit
