Engage students with a striking demonstration of air ionisation using the UNILAB Spark Discharge Apparatus. Designed for advanced physics lessons, it visually and audibly shows how alpha particles ionise air, creating a path for bright sparks and crackling sounds. Ideal for Key Stage 5 and college-level atomic physics studies.

• Includes clear operating instructions for safe use.

• Demonstrates the effect of alpha particles on air ionisation.

• Requires separate alpha source, EHT power supply, and EHT safety leads (not included).

• Suitable for classroom demonstrations in secondary schools and colleges.

• Robust construction for repeated educational use.

• Requires the following equipment:

  • An alpha radioactive source: B8A49591

  • EHT power supply (coming soon)

  • EHT Safety Lead - B8R05926 & B8R05927
