Vane wheel device is used for demonstrating air and heat flows generated by a burning candle, water vapour or other heat sources. Made of Aluminium and mountable on a long needle.

Supplier: MOLLER THERM

Radiometer according to Crookés. Consists of a glass container on foot with low air pressure and needle-bearing spinner with four vertical mica discs. The discs are black on one side and shiny on the other. The discs thus absorb radiation differently. The higher temperature of the dark side means that the air molecules get greater kinetic energy in collision with the dark side of the discs than with their shiny side. The result is that the spinner starts to rotate.

Supplier: 3B Scientific

Tube holder to support all S series 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. The base plate has a slot for attaching the Helmholtz pair of coils S.

Supplier: 3B Scientific

Function generator with external sweep function and power amplifier for use in versatile student and practical experiments covering simple harmonic oscillation, AC electricity and induction. Featuring illuminated, digital display for frequency, signal form, offset and other parameters.

Supplier: 3B Scientific

Evacuated glass flask containing i.a. electron gun with directly heated tungsten wire cathode and a cylindrical, collimating anode. The generated beam is allowed to stroke along a semi-transparent mica disc in the center of the tube. Luminescent coating on the front of the disc makes the beam appear. Two of the edges of the back are provided with graduated scales.

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.
