Ideal for advanced physics lessons, this Perrin Teltron Tube enables students to observe and investigate the behaviour of cathode rays and the effects of electric and magnetic fields. Designed for Key Stage 5 and college use, it supports practical demonstrations of fundamental atomic physics concepts.

This highly evacuated electron tube features a focusing electron gun, a fluorescent screen for clear beam visibility, and an integrated Faraday pail for charge experiments.

• Includes spherical glass body with cylindrical neck and diode electron gun

• Fluorescent screen set at 45° for easy observation of electron paths
