MILLIKANS APPARATUS: Observes Brownian motion

Designed for instant success in performing Millikan’s experiment of charged particles. Brownian motion can also easily be observed. With minimum of preparation the tiny particles are very easily seen and measurements taken. Supplied complete with calibrated telescope, cell with viewing windows, atomiser and injection device, polarity reversing facility, voltage adjustment control and bottle of 1 micron dia. latex spheres. Power supply required – 300-volts/DC at 1mA and 12-volt/AC or DC at 3A.
