Hooke's Law Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-ELA-5350
Jlab Export is a leading Hooke's Law Apparatus Manufacturer,and suppliers in India
Hooke's Law Apparatus (code EL-ELA-5350) is a bench stand for showing how the extension of a spring depends on the load hung from it, within the elastic limit, in school and college physics practicals. A spring hangs from a collar at the top of a vertical metal rod, and a pointer on the weight hanger moves along a 12 cm mirror scale. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Hooke's Law Sets?
| Model | Scale | Base and stand | Weights and other listed details |
|---|---|---|---|
| This apparatus (EL-ELA-5350) | Graduated mirror scale, 12 cm, adjustable along the rod | Metal rod on a stable base, spring hung from a top collar | Set of slotted weights; weight hanger with built-in pointer |
| Hooke Law Apparatus | 150 mm adjustable mirror scale marked in millimetres | Wooden base, 300 mm rod with a hook for the spring | 250 g slotted weight set; mass hanger with indicator |
| Hookes law | Adjustable mirror millimetre scale | Heavy base | Four 50 gram slotted weights; spiral spring with indicator and weight hanger; also listed for simple harmonic motion and potential energy; instructions included |
Choose this apparatus for a straightforward load–extension practical on a metal rod stand whose scale slides to suit the spring. The other Hooke Law Apparatus lists a longer 150 mm scale on a wooden base with a 250 g weight set, while the Hookes law set lists four 50 gram weights and is also described for oscillation studies.
What Is the Hooke's Law Apparatus Used For?
Hooke’s law states that, up to the elastic limit, the extension of a spring is directly proportional to the load on it. With this physics lab equipment students carry out the class 11 practical to find the force constant of a helical spring by plotting a graph between load and extension, and younger classes can use it to see elastic behaviour for themselves. Colleges use the same set-up for introductory mechanics labs.
To run the experiment, hang the spring from the collar, fit the weight hanger and slide the mirror scale until the pointer sits near a convenient mark. Note the zero-load reading, then add slotted weights one at a time and record the pointer position after each addition, looking so that the pointer covers its own reflection in the mirror to avoid parallax. Plot load against extension: the straight part of the graph confirms the law, and its slope gives the force constant. Remove the weights at the end to check that the pointer returns to its first reading; if it does not, the spring has been stretched beyond its elastic limit.
What to Specify When Ordering
- Quantity — the minimum order is 10 sets; many labs plan one set per group of students.
- Spare springs and weights — extra springs or slotted weight sets can be added to the same enquiry.
- Model — this rod-and-collar set or one of the alternatives in the comparison above.
Frequently Asked Questions
What does this apparatus demonstrate?
It shows the relationship between the load on a spring and the extension it produces, within elastic limits — the basis of Hooke’s law and of finding a spring’s force constant.
Are the slotted weights included?
Yes. The set comes with slotted weights and a weight hanger. The listing does not state the individual masses, so ask JLab if your practical needs particular values.
Why does it have a mirror scale?
The mirror lets students line up the pointer with its own reflection before reading, which removes parallax error. The scale is 12 cm long and can be moved up or down the rod.
How does it differ from the other Hooke's law sets JLab lists?
This one hangs the spring from a collar on a metal rod with a 12 cm mirror scale. The other Hooke Law Apparatus lists a 150 mm scale, wooden base and 250 g weight set; the Hookes law set lists four 50 gram weights and is also described for simple harmonic motion.
What should an export quotation request include?
The quantity, destination country and port or city, delivery terms such as FOB or CIF, packing or labelling needs, any spare springs or weights, and a tender reference if applicable.
Who manufactures this apparatus?
Jain Laboratory Instruments Pvt Ltd (JLab) builds it at its works in Ambala, Haryana, India, and supplies it directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a physics lab instruments manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The rod stand, scale, spring and hanger are assembled at JLab’s own works rather than bought in from a trader, so schools, colleges, dealers and importers deal directly with the manufacturer, each set is visually inspected before dispatch, and spares and repeat orders come from the same source. JLab exports worldwide and ships to buyers in every region — including, for example, Gabon in Central Africa, Austria in Western Europe, Thailand in Southeast Asia, Barbados in Central America and the Caribbean, and Bahrain in the Middle East. Tender buyers can refer to the JLab lab tenders page.
Springs and Weights
- Springs Steel — a steel spring for Hooke’s law, spring constant and spring–mass oscillation practicals.
- Slotted Weights with Hanger — a slotted weight stand with carrying handle for physics demonstrations.
- Helical Spring — a coiled compression spring for comparing compression with extension.
