Physics Educational Materials
Avantor offers a complete catalog of instruments and tools useful for demonstrating key, basic concepts of physics that are applicable to everyday life both in and out of the laboratory. Demonstrate core ideas such as acceleration down a plane, friction, potential and kinetic energy, electrical conductivity, magnetic fields, wavelengths and velocity of sound, and more. Durable educational materials are designed for heavy use with consistent levels of handling, and all models are easy to use.
Electron deflection tube D
Supplier: 3B Scientific
Highly evacuated electron tube with focusing electron gun and fluorescent screen (90×60 mm) 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 an optional Helmholtz coil pair D. 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.

Electron diffraction tube D
Supplier: 3B Scientific
Highly evacuated electron tube for determining the wavelength of electrons as a function of the anode voltage from the radii of the diffraction rings and the distance between the lattice planes of graphite (Debye-Scherrer-diffraction) and rendered visible on a fluorescent screen. Also intended for determining the wavelengths of monochromatic radiation at different anode voltages from the radii of the diffraction rings and the lattice plane spacing of graphite, as well as confirming de Broglie’s hypothesis.
