"Tubes"

The Student Coin and Feather Tube shows the two items in a vacuum, falling at the same rate.

Hertz electron tube for quantitative investigations of Inelastic collisions of electrons with inert gas atoms.

Bulk rolls for easy length adjustment.

Investigate the spectral pattern of different gases.

Students measure pressure with a precision manometer.

To Accompany Your Tuning Fork!

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. The electron beam can be deflected electrically in the electric field of the built-in plate capacitor, and magnetically by using the Helmholtz coil pair (not included). By adjusting the electric field so that it cancels the magnetic deflection, it is possible to determine the specific charge (e/m) and the velocity of the electrons.

High quality and reliable.
