Expansion of Liquid Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-4552
Jlab Export is a leading Expansion of Liquid Apparatus Manufacturer,and suppliers in India
Expansion of Liquid Apparatus (code EL-SLE-4552) demonstrates that different liquids expand by different amounts when heated through the same temperature range. Glass capillary tubes of equal bore, each with a bulb at the bottom, are mounted on a frame so the bulbs can be immersed together in hot water and the rise in each tube compared directly. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with the Expansion of Liquids Apparatus?
| Model | Tubes and bulbs | Heating arrangement | Other listed details |
|---|---|---|---|
| Expansion of Liquid Apparatus (EL-SLE-4552) | Capillary tubes of equal bore with bulbs at the bottom | Frame for immersing the bulbs in hot water | Supplied with accessories |
| Expansion of Liquids Apparatus | Five bulb tubes | Frame supported in a water trough | Sliding clip arrangement; removable bulbs with a funnel top for easy filling |
Both show the same effect. The five-tube model lists a water trough and removable, funnel-topped bulbs for quick refilling; this apparatus lists equal-bore capillaries and a frame for immersing the bulbs in hot water, so ask JLab for its tube count and accessory list if you need to match a practical manual.
What Is the Expansion of Liquid Apparatus Used For?
Each bulb is filled with a different liquid — for example water, coloured alcohol and glycerine — to the same starting mark. When the bulbs go into hot water together, every liquid receives the same rise in temperature, and because the capillaries share the same bore, the height each column climbs is a direct comparison of how much each liquid has expanded. Students see that liquids differ in their coefficient of volume expansion, and a sharp-eyed class will notice the levels dip slightly at first as the glass bulbs warm and expand before the liquids do — the difference between real and apparent expansion. It supports the thermal expansion part of class 11 physics and junior science lessons on how heat changes the volume of liquids, and is standard physics lab equipment for schools that teach thermometry.
Remove any air bubbles before marking the starting levels, use hot water rather than a flame, and keep flammable liquids such as alcohol away from burners. Let the glass cool before emptying, rinse each bulb and tube with water, and store the apparatus upright on its frame.
What to Specify When Ordering
- Quantity — the minimum order is 10 units.
- Tube count and accessories — ask JLab to confirm the number of tubes and the accessories included with the current model.
- Thermometers and heating — a thermometer and a vessel for hot water, if you need them.
- Delivery — destination, delivery terms such as FOB or CIF, and any tender reference.
Frequently Asked Questions
What does this apparatus show?
That different liquids expand by different amounts over the same temperature range. The equal-bore capillaries make the comparison fair, so the tallest column belongs to the liquid that expands most.
Why do the levels sometimes fall before they rise?
The glass bulbs heat and expand first, briefly giving the liquid more room. Once the heat reaches the liquid, its larger expansion takes over and the columns climb — a neat demonstration of apparent versus real expansion.
How many tubes does it have?
The listing does not state the number of tubes. Ask JLab to confirm it, together with the accessory list, when you request a quote.
Which liquids can I compare?
Any liquids that are safe to warm in glass, such as water, alcohol and glycerine. Colouring clear liquids with a drop of dye makes the columns easier to see.
What is the minimum order and dispatch time?
The minimum order is 10 units, sold individually. Dispatch is usually within 7–10 working days after a visual inspection of each apparatus; export transit depends on the destination.
Who manufactures it?
Jain Laboratory Instruments Pvt Ltd (JLab), at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of heat, light, electricity and general physics teaching apparatus in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The apparatus is assembled at JLab’s own works rather than bought from a trader, so schools, colleges, dealers and importers buy factory-direct; each set is visually inspected before dispatch, and repeat orders and replacement parts are handled by the manufacturer. The company holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise and exports under Importer-Exporter Code 3317504552. Buyers in every region can order from JLab — Uruguay in South America, Cyprus in Southern Europe, Guatemala in Central America and the Caribbean, Ghana in West Africa and the USA in North America are examples. See the JLab lab tenders page for tender information.
