Tube holder to support all S series (student) electron tubes for easy and safe operation. The five pin sockets for the tube are concealed inside the tube holder. A cathode protection switch is integrated into the tube holder, to protect the heated cathode from excessive voltage.
Tube holder made of robust plastic for holding D-series electron tubes. Stand has a wishbone, 360deg rotating clamp made of heat-resistant plastic. On rubber feet to prevent slipping. Dimensions: approx. 230x175x320 mm3 Weight: approx. 1.5 kg
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.
