Molecular Model Large Demonstration Set – Version 2 [2338]

The Large Demonstration Molecular Model Set – Version 2 is a highly versatile teaching resource designed to help whole classes clearly visualise and understand molecular structure and bonding. Ideal for secondary and post‑16 chemistry, this large‑scale modelling kit enables teachers to construct oversized molecular structures that can be easily seen from anywhere in the room.

With this set, you can build an extensive range of organic and inorganic molecules including hydrocarbons, alcohols, amines, acids, bases, carbohydrates, benzene, chlorinated compounds and more. Teachers can also demonstrate key chemical concepts such as rotating single bonds, rigid double and triple bonds, structural isomers, optical isomers, VSEPR geometries, and the chair–boat flip of cyclohexane.

Why This Set is Ideal for Classroom Demonstration

• Large‑scale models can be clearly seen from the back of the classroom
• All atoms and bonds are to scale (8.5 cm per 100 pm)
• Sturdy pegs allow all atoms and bonds to connect at realistic bond angles
• Durable plastic parts ensure long‑lasting classroom use
• Easy to assemble, adjust, and dismantle
• Fully compatible with a wide range of supplementary atoms, bonds & orbitals

Set Contents

The Large Demonstration Set includes everything needed to model complex structures:

• 70 atom spheres with integrated bonding pegs
• 90 plastic bonds for single, double and triple bonding arrangements

These components allow teachers to build an exceptional variety of molecular models for both organic and inorganic chemistry.

Ideal for School & College Chemistry Lessons

This demonstration kit is perfect for GCSE, A‑Level and introductory university chemistry, supporting visual and practical learning across molecular structure, bonding, and stereochemistry. It is invaluable for:

• Demonstrating bonding (single, double, triple)
• VSEPR theory and molecular geometry
• Building ring structures such as benzene and cyclohexane
• Showing isomerism – structural & optical
• Explaining functional groups and organic families
• Discussing polarity, shape, hybridisation and more

Engaging, robust, and highly adaptable, the Molecular Model Large Demonstration Set – Version 2 is an essential tool for chemistry teachers aiming to bring molecular structures to life in the classroom.
