Choose one, or all six of our Specific Structures models to introduce concepts of unit cells, coordination numbers and crystal systems; or as valuable aids when discussing solid state, X-ray diffraction, cohesive forces and other topics. (The characteristic unit cell can be indicated by colored thread or colored connecting rods.)
The models comprise 1?, color-coded, wooden spheres attached by sturdy metal rods. Dimensions along each edge vary from 4? to 9?, depending upon the structure represented.
Each model is furnished completely assembled. A comprehensive, illustrated teacher’s guide explains the fundamental crystal systems and discusses the use of each model.
