Description
The IEC linear expansion apparatus is a classic teaching instrument for measuring and comparing thermal expansion by heating metal tubes with steam. Steam is passed through the tube, producing a controlled temperature rise, and the resulting change in tube length is measured using a precision engineering dial indicator with 0.01 mm resolution, supporting repeatable, quantitative expansion comparisons.
A thermometer is included to monitor the tube temperature in both cold and hot conditions, allowing students to record temperature change alongside measured extension for standard linear expansion calculations and consistent lab reporting. Steam for the apparatus can be supplied from a boiling flask fitted with a side branch to carry steam to the tube, using common lab glassware arrangements.
Important use note: steam and hot metal surfaces present burn hazards, use standard heat and steam handling procedures during operation.
