Build models of organic and inorganic molecules that can be seen from the back of the class.

• With large spheres 44 mm diameter and smaller spheres 25 mm for hydrogen
• The versatile bonding peg system allows all the larger spheres to be joined in sp, sp2, sp3, dsp3 or d2sp3 configurations
• Demonstrate single, double and triple bonds, isomers, ring structures, the chair-boat 'flip' of cyclohexane and VSEPR theory

This system offers great flexibility for teachers and lecturers. The models are easy to handle, build and take apart. The highly durable plastic parts create long-lasting models.
