Ring and Ball Apparatus Manufacturer,Supplier and Exporter in India
Product Code : JL-LEP-10422
The Ring and Ball Apparatus from Jaincolab is used to demonstrate thermal expansion and contraction of a metal. As a school laboratory equipment manufacturer, Jaincolab supplies this ring and ball set as part of a wider range of physics lab equipment used for teaching heat concepts in schools and colleges across India. It comprises a captive brass ball secured to a mounted brass ring by a chain, so students can see the ball pass through the ring at room temperature and fail to pass through once heated.
