Cochranes molecular models

A basic set in the Orbit molecular building system without workbook for self-directed work. Contains sufficient atoms and bonds to make simple models to understand chemical structures including: hydrocarbons, ring structures, alcohols and esters, simple inorganic molecules and the basic molecules of life - sugars, amino acids, glycerol and fatty acids.

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.
