Van De Graaff - Spare Combs Rub Upgrade Kit

This Spare Combs Rubber O-Ring Upgrade Kit is designed to support the maintenance and performance of IEC Van De Graaff Generators. Combs play a critical role in transferring electrostatic charge from the belt to the dome, and this kit includes durable rubber O-rings to ensure a secure and precise fit. Over time, wear and tear on these small components can affect overall performance, so this upgrade kit helps extend the life of your generator and maintain consistent charge output. It's an essential part of keeping high-voltage demonstrations safe and effective.

Educational benefits:

• Ensures proper function of electrostatic charge transfer within the generator
• Supports student understanding of internal generator components
• Reinforces the concept of electrical grounding and charge collection
• Encourages preventative maintenance as part of science lab best practice
• Promotes discussion on materials used in high-voltage applications

Classroom activity ideas:

• Demonstrate how worn or missing combs affect the generator's performance
• Allow students to replace combs and o-rings as a practical STEM task
• Incorporate into a lesson on how geometry (sharp points) enhances electric field intensity
• Use to explain how charge is collected and delivered to the dome via comb design
• Compare results before and after installation of the new kit for a maintenance-focused experiment
