Unit Class Demonstration SetThis set is a multi-purpose design intended primarily for showing VSEPR theory in a classroom setting. It is best used for small molecules but can also show simple ring structures. It can also be used to build the seven basic crystal structures (Bravais lattices) but only a few at a time. It is not recommended for large organic or biochemical structures or for chair-boat flips.
 Unit Cells Model KitThis kit is dedicated to showing the unit cells of the 7 basic crystal systems. These large models are ideal for demonstration purposes. The smallest model, the "cubic", measures 155mm across (~6.25").
