Continuous cloud chamber
Continuous cloud chamberContinuously operating cloud chamber for displaying particle tracks. With the aid of approx. 50 g dry ice and 1-2 mL of denatured alcohol, particle tracks can be observed for up to 30 minutes.
Control transformer
Control transformerUsed as a power supply for spectral lamps in connection with spectral lamp housing 283050 or 283065, and mercury lamps 286500 and 286000 fitted in holder 287000.
Convection chamber, air
Convection chamber, airThis convection chamber is designed for demonstrating convection processes in air. The simple, illustrative experiments help to clearly explain the principles of convection and facilitate discussion of how high and low pressure and winds arise.

Coupled harmonic oscillators f. airtrack
Coupled harmonic oscillators f. airtrackCoupled harmonic oscillators allow harmonic oscillations to be studied on the air track. Up to 5 carts can be connected to study coupled harmonic oscillations or wave propagation. A single cart can be used with one or more springs in order to study a simple harmonic oscillation.
Crooke’s radiometer
Crooke’s radiometerThis radiometer can be used to demonstrate that radiation energy (e.g. heat) can be converted into movement energy, kinetic energy.
Current balance
Current balanceFor measuring the force between a current-carrying conductor and a magnetic field.
Current balance, angle-dependent
Current balance, angle-dependentFor measuring the force between a current-carrying conductor and a magnetic field relative to the angle between the current direction and the magnetic field.
