Unit Large Demonstration Set

126.70 - 199.90 each

For large-scale, durable molecular models of organic, inorganic and biochemical molecules

Full Description Resources Customer Reviews

With the Unit Large Demonstration molecular model set you can demonstrate 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.

This 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 across all levels of education:

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

Total Contents: 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.
