Eduscope India is a leading Pullinger Expansion Apparatus
Quick Answer: The Pullinger Expansion Apparatus is used to determine the coefficient of linear expansion of a solid metal rod, making it a practical choice of physics lab equipment India schools and colleges use for heat-expansion experiments — a durable, export-ready pick for institutions sourcing laboratory equipment school India wide and overseas.
Construction and Specifications
The apparatus consists of a tube fitted with a riffled nozzle at each end, facing opposite directions, for the inlet and outlet of steam. It is supplied complete with three different metal rods — iron, aluminium and brass — so students can heat each rod through the same rise in temperature and compare their different linear expansion, clearly demonstrating that different metals expand by different amounts under identical heating. Because the apparatus is heated by passing steam through it, it is used together with EduScope India's Steam Generator, which supplies the continuous steam source required for the experiment.
