Pullinger Expansion Apparatus
Product Code : EL-LE-16344
Eduscope India is a leading Pullinger Expansion Apparatus
Quick Answer: The Pullinger Expansion Apparatus is a steam-heated linear expansion apparatus with a micrometer screw head reading to 0.01 mm, supplied complete with copper, brass and steel test rods.
As a physics lab equipment India apparatus, EduScope India supplies this Pullinger Expansion Apparatus for measuring the linear expansion of metal rods under heating. It has two cast metal legs joined by a pair of plated metal rods, each leg horizontally supporting the ends of a plated brass tube about 50 cm long. The tube carries a riffled nozzle near each end, facing opposite each other, for use as the steam inlet and outlet, along with a further outlet at the centre fitted with a holed rubber bung for inserting a thermometer to measure the internal temperature. The test rod sits inside the brass tube, supported in rubber bungs at each end, with a micrometer screw head reading to 0.01 mm fitted at one end to measure expansion precisely. 4 mm terminals are provided on each leg for connecting an electric bell or galvanometer to indicate the make or break of contact as the rod expands, and the apparatus is supplied complete with three metal test rods: one each of copper, brass and steel. It pairs naturally with EduScope India's Bucket and Cylinder for a fuller range of physics lab equipment used in mechanics and thermal-expansion experiments.

EduScope India supplies the Pullinger Expansion Apparatus and related laboratory equipment to school and college physics laboratories across Peru, Colombia, Ecuador and Bolivia, supporting thermal-expansion experiments throughout the Andean region of South America.
The apparatus is also supplied as part of bulk orders for CSR-funded college and laboratory-chain equipment programmes, with EduScope India assisting institutions in specifying complete laboratory equipment sets.
For laboratories building a complete mechanics and thermal-expansion experiment setup, the Pullinger Expansion Apparatus works well alongside the Bucket and Cylinder, both available in EduScope India's Laboratory Equipment range.
