Energy Tube, teaching resource for an array of scientific concepts: open and closed circuits, conductors vs. Insulators, light waves, sound waves,currents, and energy, When a conductor touches both of the electrodes on tube, tube emits a sound and flashing red/green/blue LED lights
Highly evacuated electron tube with focusing electron gun and fluorescent screen inclined relative to the beam axis, so that the path of the beam can be seen and the effects of electric and magnetic fields can be studied.
Induction Tube Apparatus With 6 Coils, Tube Dimensions (L X D): 1500 X 20 mm, Coil Width: 10 mm, Distance Between Coils: 19 Cm, Due To The Magnet'S Free-Fall Acceleration Caused By Gravity, The Voltage Peaks Increase Proportionally With The Time.
Resonance Tube Apparatus, Long version, Material: Acrylic, Mounted on retort stand with clamp and boss, with metal vessel, connecting tubing and spring clip supported on iron ring, Dimension: 120cm
Spectrum Tubes - Sulphur, Length 26Cm, High-Quality Design For Greater Viewing Area, Effectively Demonstrate The Spectral Lines Of Pure Substances, For Use With Spectrum Tube Power Supply
Spectrum Tubes Deuterium, glass tubes approximately 10-1/4in (260mm) long, central capillary portion approximately 3-1/2in to 4in (90-100mm) long with electrodes sealed at both ends and connected to lead wires protected by metal caps.
