Descripción

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

Make models of amino acids, monosaccharides, glycerol, fatty acids, steroids, purines and pyrimidines, peptides, disaccharides, lipids, nucleosides, nucleotides, proteins, polysaccharides, nucleic acids. This group set can be used to make multiple models of small compounds and large tertiary structures. Includes instruction/activity booklet. Includes 5 instruction/activity booklets.
