Expansion Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-5771
Jlab Export is a leading Expansion Apparatus Manufacturer,and suppliers in India
Expansion Apparatus (code EL-SLE-5771) is a simple version of the thermal expansion apparatus, designed to let students compare how much common metals expand when they are heated, in school and college physics lessons on heat. Seeing different metals grow by different amounts for the same heating makes the idea of a material’s expansion coefficient concrete. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Thermal Expansion Apparatus?
| Model | What it shows | Listed details |
|---|---|---|
| This apparatus (EL-SLE-5771) | Comparison of the expansion of common metals | Simple version |
| Linear Expansion Apparatus | Coefficient of linear expansion of a metal rod | Steam-heated tube; micrometer with bell or galvanometer contact signal; iron, copper and brass rods supplied |
| Ball and Ring Apparatus | Expansion of a solid on heating | Brass ball on a handle, chained to a brass ring |
| Bimetallic Strips with a Wooden Handle | Unequal expansion bending a strip | Joint-less copper and steel strips |
Choose this apparatus for a straightforward side-by-side comparison of metals. For a measured coefficient of linear expansion, the steam-heated apparatus with a micrometer is the one to order; the ball and ring and the bimetallic strip are quick qualitative demonstrations.
What Is an Expansion Apparatus Used For?
Most solids expand when heated, but not all by the same amount: for the same rise in temperature, some metals grow noticeably more than others. A comparison apparatus lets a class see this directly and connect it to the thermal-expansion topic of class 11 physics and to everyday engineering — gaps left between rails and in bridges, and bimetallic strips in thermostats and fire alarms. Let the apparatus cool fully before handling it after a run, and keep the metal parts clean and dry between lessons.
Frequently Asked Questions
What does this expansion apparatus demonstrate?
That common metals expand by different amounts when heated through the same temperature rise, so students can compare them side by side.
Which metals are supplied, and how is it heated?
The listing does not state the metals, the heating method or the dimensions. Tell JLab which metals you want to compare and how your lab heats apparatus, and it will confirm what is supplied.
How is it different from the linear expansion apparatus?
This is a simple comparison version. The linear expansion apparatus heats a rod with steam and measures its growth with a micrometer, so students can calculate the coefficient of linear expansion.
Who manufactures this apparatus?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian maker of heat, mechanics and general physics apparatus for schools and colleges, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The apparatus is built at JLab’s own works, not bought from a trader, so schools, colleges, dealers and importers buy straight from the manufacturer, each unit is inspected by eye before dispatch, and repeat orders go back to the same works. JLab exports worldwide and ships to buyers in every region — for example Madagascar in East Africa, Mexico in North America, Bangladesh in South Asia, Cambodia in Southeast Asia and Taiwan in East Asia. For tenders, see the JLab lab tenders page.
