cochranes Unit Large Demonstration Set - Plastic Bonds
cochranes Unit Large Demonstration Set - Plastic Bonds
Product code: HE1603718
Product Description
The Unit Molecular building system features large (44mm diameter) spheres in seven colours to represent different atoms plus a 25mm diameter white sphere to represent Hydrogen atom. Sturdy pegs allow you to make any bond angle which can then be joined with flexible vinyl bonds.
The large demonstration molecular model kit lets you demonstrate molecular shapes with rotating single bonds and non rotating double and triple bonds, structural isomers, ring structures, the chair-boat 'flip' of cyclohexane and VSEPR theory.
The kit allows models of hydrocarbons, alcohols, amines, organic and inorganic acids and bases, carbohydrates, benzene, chlorinated molecules, inorganic molecules and many more to be produced, which the whole class can see!
Suitable
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
Contains : 70 atom spheres with bonding pegs and 90 plastic bonds.
