Ring and Ball Thermal Expansion Apparatus

Our Ring And Ball Thermal Expansion Apparatus is precision designed equipment fabricated using high grade brass. It is used to demonstrate the thermal expansion (cubical expansion) of metals. Highly acknowledged in industry, this apparatus has a brass ring through which the brass ball will pass when both are at the same temperature, be it hot or cold. However, in case, the ball is heated but not the ring, the ball will not pass through it. A wooden handle is provided to both ball and ring so that it is easy to hold.
