Description
The Gravesande’s Brass Ball and Ring Apparatus, also known as a brass ball and ring thermal expansion demonstrator, is designed to show the effect of temperature change on metal dimensions. This classic apparatus uses a brass ball and matching brass ring to demonstrate thermal expansion and contraction in a clear, visual way. When the ball is heated, it expands and can no longer pass through the ring. When the ring is chilled in ice, the ring contracts and the ball may also be prevented from passing through. A chain joins the ball to the ring so the two parts cannot become separated during classroom use, storage or repeated demonstrations.
The IEC item is carefully machined and matched for size so that the experiment works reliably. Correct matching is important because poorly made ball and ring sets may not show the intended result clearly. This apparatus is suitable for school science laboratories, university teaching laboratories and physics classrooms studying heat, solids, expansion, contraction and particle model explanations. Users should confirm the approved heating method, cooling method, handling procedure and supervision requirements before use.
The brass ball and ring may become very hot during the demonstration. Use tongs, heat-resistant gloves or approved handling tools, and allow the apparatus to cool before storage. Do not touch heated metal directly, overheat the apparatus, quench hot metal unsafely or use near flammable materials without proper controls. This product is intended for laboratory or educational settings only and should be used under appropriate teacher or laboratory supervision. This item is supplied as the brass ball and ring apparatus only. Burner, lighter, ice, beaker, tongs, heat mat, gloves, PPE and additional accessories are not included unless specified separately.
LabChoice Australia supplies Gravesande’s Ball and Ring Apparatus and physics demonstration equipment for school science laboratories, university teaching laboratories and educational facilities requiring practical tools for thermal expansion experiments.
