Easy and safe way to hold and power your tubes.

Tube holder is made of robust plastic for holding D-series electron tubes. Stand has a wishbone, 360° rotating clamp made of heat-resistant plastic and two base holes for affixing the Teltron Helmholtz Coils. On rubber feet to prevent slipping.

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.
