IEC Millikans Apparatus with Power SupplyOrder code: AP2131-001
This apparatus is used to perform Millikan's experiment with charged particles moving in an electric field or to observe Brownian motion. Complete with a telescope and graticule for focusing through one of the two windows provided. A tiny amount of latex is atomised and passed through a latex rubber tube which induces a static charge. The particles pass through a hypodermic needle into the cell where they cross the path of an intense white light focused at the centre of the cell. The charged latex particles, with a diameter of approximately 1 micron, present at the focal plane near the centre of the cell, can be clearly seen through the telescope as bright dots.
