Brass Ring and Ball Manufacturer,Supplier and Exporter in India
Product Code : EL-LS-5041
Jlab Export is a leading Brass Ring and Ball Manufacturer,and suppliers in India
Brass Ring and Ball (code EL-LS-5041) is a demonstration apparatus for thermal expansion, made of brass: a brass ball and a brass ring, each mounted on a handle. At room temperature the ball passes easily through the ring; once the ball is heated over a flame it expands and no longer fits. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Ball and Ring Sets?
| Model | Ball and ring | Mounting |
|---|---|---|
| This set (EL-LS-5041) | Brass ball and brass ring | Each mounted on a handle |
| Ball and Ring Physics | Brass ball and brass ring | Each on a brass rod with a wooden handle |
| Ball and Ring Apparatus | 19 mm brass ball and brass ring | Ball on a plastic handle; ring joined to it by a chain |
All three show the same effect. Choose this set for an all-brass ball and ring on separate handles; choose the chained model if you want the two parts kept together.
What Is the Brass Ring and Ball Used For?
Most solids expand when heated, because their particles vibrate more strongly and take up slightly more space. The change in a metal ball is far too small to see by eye, but the ring turns it into a clear yes-or-no result: the cold ball slips through, the hot ball will not pass. When the ball cools it contracts again and passes through once more, so the same apparatus shows contraction as well. Teachers use it in physics demonstration lessons on heat and to explain everyday examples such as the expansion gaps left in railway tracks and bridges.
What to Specify When Ordering
- Model — this all-brass set, the wooden-handle Ball and Ring Physics set or the chained Ball and Ring Apparatus.
- Quantity — one for a teacher demonstration, or more for student groups.
- Related apparatus — bimetallic strips and burners are separate items that can be quoted on the same enquiry.
Frequently Asked Questions
How does the brass ring and ball show thermal expansion?
At room temperature the ball passes easily through the ring. After the ball is heated over a flame it expands and no longer fits, showing that the metal has grown slightly in size.
Does the ball pass through the ring again after cooling?
Yes. As the ball cools it contracts back to its original size and passes through the ring again, which demonstrates contraction on cooling.
What information is needed for an export quotation?
Give the quantity, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), any packing or labelling instructions and a tender reference if one applies.
Who manufactures the Brass Ring and Ball?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of physics demonstration apparatus and school lab equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The ring and ball is made at JLab’s own works, not bought in from a trader, so schools, colleges, dealers and importers order it factory-direct. JLab exports worldwide and ships to buyers in every region — for example the Czech Republic in Eastern Europe, Lebanon in the Middle East, Guatemala in Central America and the Caribbean, Tonga in Oceania and South Korea in East Asia. Tender buyers can refer to the JLab lab tenders page.
Related Heat and Expansion Apparatus
- Ball and Ring Physics — a brass ball and ring on brass rods with wooden handles, showing expansion and contraction.
- Ball and Ring Apparatus — a brass ball on a plastic handle with the ring attached by a chain.
- Bimetallic Strips with a Wooden Handle — copper and steel strips that bend when heated.
- Compound Bimetal Bar — a bimetallic strip on a wooden handle that bends because the two metals expand differently.
