Ball and Ring Apparatus
Product Code : EL-H-10395
Ball and Ring Apparatus from Lab Exports demonstrates thermal expansion of solids using a captive 19 mm brass ball secured by a chain to a mounted brass ring, both fitted on rods with wooden handles. The ball passes freely through the ring when cold but will not pass through once heated, giving students a direct, visible demonstration of expansion. Lab Exports manufactures and exports this apparatus from India to schools, colleges and laboratories worldwide.
