About Eisco Labs Large Needle Electroscope

Extra large apparatus ideal for classroom demonstrations Great tool to discover electrostatic principles such as conduction, induction and coulomb repulsion Clear front pane lifts up to allow easy application of ionizing materials Eisco Labs Large Needle Electroscope This extra large electroscope is ideal for classroom demonstrations of electrostatic principles. A light-weight metal vane is used as a pointer in the electroscope. This light weight metal blade deflects when the electroscope plate is charged. A transparent scale is provided to measure the angle of the deflection. Front glass window slides up to allow insertion of ionizing material in chamber. This electroscope comes with two accessories: an electrophorus disc and a spherical electrode. Assembled, the electroscope measures 9.75 x 8 x 4.75 inches.
