Tel tron Electron Diffraction Tube D
Product Code : JA-APE-7300
The Tel tron Electron Diffraction Tube D (SKU JA-APE-7300) is a highly evacuated electron diffraction tube that shows electrons behaving as waves. A beam passes through polycrystalline graphite and forms diffraction rings on a fluorescent screen, the Debye-Scherrer pattern. JaincoLab supplies this D-series tube for modern physics practicals in colleges and universities, where it is used to relate electron wavelength to the accelerating voltage and to test the de Broglie hypothesis.
Specifications
The tube sends electrons through polycrystalline graphite and displays the resulting interference rings on a fluorescent screen; the ring radii and the lattice plane spacing of graphite give the electron wavelength, while voltages and dimensions are confirmed on the quotation.

Experiments with the electron diffraction tube
Colleges use the tube to show that electrons diffract like waves, to measure how the ring radii change as the anode voltage is varied, and to compare the wavelength found from the rings with the value predicted by the de Broglie relation.
- Demonstrating the wave nature of electrons with Debye-Scherrer rings
- Finding the electron wavelength from the ring radii and the graphite lattice plane spacing

Scope of supply and ordering
One Tel tron Electron Diffraction Tube D is covered by this listing. It mounts on the Tel tron Tube Holder D, a separate listing, and the power supply needed to operate the tube is not part of this listing. Accessories, spares and quantities are confirmed on the quotation.
Minimum order quantity, lead time and packing for the tube are confirmed on each quotation according to the quantity and the delivery destination. JaincoLab quotes single tubes and department sets, supplies bulk college and tender orders, and exports to Africa, the Middle East and South and South-East Asia.
Frequently asked questions
What does the Electron Diffraction Tube D demonstrate?
It shows that electrons behave as waves: after passing through polycrystalline graphite they form Debye-Scherrer diffraction rings on the fluorescent screen.
How is the electron wavelength found?
The wavelength is calculated from the radii of the diffraction rings and the lattice plane spacing of graphite, and it can be measured at different anode voltages to test the de Broglie hypothesis.
Is there an S-series version?
Yes. The Tel tron Electron Diffraction Tube S is listed separately for laboratories that use the S-series holder and coils.
