114.00 - 180.00 each

Create large-scale durable models of organic, inorganic and biochemical molecules for front-of-class demonstration.

Full Description Resources Customer Reviews

With the Unit Large Demonstration Set you can show molecular shapes with rotating single bonds and non-rotating double and triple bonds, structural isomers and optical isomers, ring structures, the chair-boat ‘flip’ of cyclohexane and VSEPR theory.

The set allows you to make 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!

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

Both sets contain 70 atom spheres with bonding pegs and 90 rigid and flexible bonds. The rigid bonds are either made of metal, giving maximum rigidity, a smooth fit and sleek appearance or of plastic, giving convenience and durability at a reduced cost.
