Tel tron Electron Diffraction Tube S
Product Code : JA-APE-7301
The Tel tron Electron Diffraction Tube S (SKU JA-APE-7301) is the student-series version of the Tel tron electron diffraction tube, supplied by JaincoLab. Inside the highly evacuated bulb, electrons pass through a polycrystalline graphite lattice and interfere, producing concentric rings on a fluorescent screen. Students use this S-series electron diffraction tube to see the wave behaviour of electrons directly and to measure how the wavelength depends on the anode voltage.
Specifications
In the S tube electrons are accelerated towards polycrystalline graphite, and the Debye-Scherrer rings they form on the fluorescent screen are measured; the listing does not state voltages or dimensions, and these are confirmed on the quotation.

Student experiments with the S-series electron diffraction tube
On a student bench the tube is used to observe electron interference directly, to record the diameters of the rings at several anode voltages, and to check that the calculated wavelength follows the de Broglie relation.
- Observing Debye-Scherrer rings as evidence that electrons have wave properties
- Measuring ring radii and calculating the electron wavelength from the lattice plane spacing of graphite
- Recording how the wavelength changes as the anode voltage is raised or lowered
- Group practicals on wave-particle duality in B.Sc and engineering physics courses
Scope of supply and ordering
The listing is for one Tel tron Electron Diffraction Tube S. The Tel tron Tube Holder S, on which the S-series tubes are mounted, is listed separately, and power supplies are not part of this listing. Accessories, spares and quantities are confirmed on the quotation.
Minimum order quantity, lead time and packing are confirmed on each quotation according to how many tubes are needed and the delivery destination. Orders for several student benches, bulk college orders and tender quantities are supplied, including export consignments to Africa, the Middle East and South and South-East Asia.
Frequently asked questions
How does the S tube differ from the D tube?
Both show electron diffraction through polycrystalline graphite. The S tube belongs to the Tel tron Student series and mounts on the Tube Holder S, while the D tube uses the Tube Holder D.
What result do students obtain?
They measure the radii of the diffraction rings and, using the lattice plane spacing of graphite, calculate the electron wavelength at each anode voltage.
Does the tube come with a power supply?
A power supply is not part of this listing. Tell us what equipment your laboratory already has and the supply needed is confirmed on the quotation.
