Slinky Spring Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-5810
Jlab Export is a leading Slinky Spring Manufacturer,and suppliers in India
Slinky Spring (code EL-SLE-5810) is a wave form helix with a 78 mm diameter that stretches from 115 mm closed to 5 m extended, used in physics lessons to show how longitudinal and transverse waves travel along a coil. Stretched across a floor or long bench, it makes compressions, rarefactions and pulses easy for a whole class to see. JLab (Jain Laboratory Instruments Pvt Ltd, Ambala, India) supplies it to schools, colleges and dealers.

What Is the Slinky Spring Used For?
Two students hold the ends of the helix on a smooth floor or bench, a few metres apart. Pushing and pulling one end along the length of the coil sends a longitudinal wave down it — bunched-up compressions followed by spread-out rarefactions — which is the model used in the class 9 chapter on sound to explain how sound travels through air. Flicking the end sideways sends a transverse pulse instead, and with one end held firmly the pulse comes back reflected and upside down. Shaking the end steadily at the right rate sets up standing waves, and stretching the helix further shows that the wave speed changes with tension. The same activities support the waves topics of class 11 physics and introductory college lessons.
Keep within the listed 5 m extension, as overstretching can leave the coils permanently bent, and avoid letting the helix tangle or kink. If it does tangle, open it out slowly coil by coil, and store it closed in its original shape.
What to Specify When Ordering
- Quantity — the minimum order is 10 units; a helix for each group of students lets everyone try both wave types.
- Material — the listing does not state the material; ask JLab if your tender or syllabus asks for a metal or a plastic helix.
- Other wave apparatus — a ripple tank, a wave motion machine or tuning forks can be added to the same enquiry.
Frequently Asked Questions
What is a slinky spring used for in physics?
It demonstrates waves. Pushing and pulling one end makes longitudinal waves with compressions and rarefactions, as in sound, and moving the end sideways makes transverse pulses, so students can compare the two.
What size is this helix?
The coil diameter is 78 mm. It measures 115 mm when closed and can be extended to 5 m.
What is it made of?
The material is not given in this listing. Ask JLab when you enquire, especially if your order specifies metal or plastic.
How do I stop it tangling?
Stretch it only along a straight line on a flat surface, keep within the 5 m extension, and close it up before lifting it. If it tangles, untwist it slowly one coil at a time.
Who supplies the Slinky Spring?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, of Ambala, Haryana, India, supplies it and quotes for it directly.
Supplier
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a laboratory and school science equipment company incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. It supplies this wave helix alongside the physics and school lab equipment it produces itself, so schools, colleges, dealers and importers can add it to one order with the rest of their apparatus, and each helix is visually inspected before dispatch. JLab exports worldwide and ships to buyers in every region — for example El Salvador in Central America and the Caribbean, Latvia in Northern Europe, Japan in East Asia, Laos in Southeast Asia and Jordan in the Middle East. Tender information is on the JLab lab tenders page.
Other Wave and Sound Apparatus
- Ripple Tank — shows refraction, diffraction and interference of water waves.
- Wave Motion Machine, Plastic — demonstrates longitudinal and transverse motion with a turning handle.
- Tuning Forks — stainless-steel forks in a case with a hammer, for sound lessons.
- Slinky Spring (steel) — a steel helix listed in a different size.
