Molecular Model Large Demonstration Set - Version 2.
With the Unit Large Demonstration Set you can build models of
hydrocarbons, alcohols, amines, organic and inorganic acids and bases,
carbohydrates, benzene, chlorinated molecules, inorganic molecules
and more - that the whole class can see!
Demonstrate rotating single bonds and non-rotating double and triple
bonds, structural isomers and optical isomers, ring structures, the chairboat
‘flip’ of cyclohexane and VSEPR theory.
This versatile system offers great flexibility for teachers and lecturers:
Structures can be seen from the back of the class
Bonds and atoms are to scale for accuracy at 8.5cm per 100pm
Sturdy pegs join all atoms and bonds at any bond angle
Easy to handle, build and take apart
Highly durable plastic parts create long-lasting models
Full range of supplementary atoms, bonds and orbitals available
Set contains 70 atom spheres with bonding pegs and 90 plastic bonds.
