Lever Apparatus
Product Code : SCL-PL-12352
Lever Apparatus (SKU SCL-PL-12352) is a 100 cm lever on which students fit a centre or off-centre pivot and hang calibrated masses to investigate first-, second- and third-class levers and the principle of moments. It serves middle-school simple-machines lessons, Class 9–11 physics and teacher-training courses. As a laboratory equipment manufacturer in India, Science Lab Supplies produces the apparatus in its Saha, Ambala works (Plot 448, HSIIDC Industrial Area) and delivers it to schools, colleges, dealers and tender contractors without a middleman.
Specifications
The lever is 100 cm long and can be pivoted at its centre or off-centre. Loads hang on both sides to balance it, and additional holes along the beam give more hanging positions. A set of calibrated masses and a heavy-duty fixing screw are included, so the apparatus is ready for moment experiments.

Applications and Experiments for the Lever Apparatus
The apparatus is used to verify the principle of moments and to compare the three classes of lever by moving the pivot, the load and the effort along the beam. It fits simple-machines chapters in middle school, turning-effect and equilibrium topics in Class 9–11, and practical sessions in teacher-training colleges.
- Middle-school science: identifying first-, second- and third-class levers and their everyday examples.
- Class 9–10 physics: verifying that clockwise and anticlockwise moments balance when the lever is level.
- Class 11 physics (rotational motion): torque and the conditions for equilibrium of a rigid body.
- Teacher-training labs: calculating mechanical advantage for different pivot and load positions.
Standard Scope of Supply
Each apparatus comes with the 100 cm lever with its centre and off-centre pivot options and additional load holes, a set of calibrated masses, and a heavy-duty fixing screw. Extra masses or hangers can be added as separate lines if a class needs more loads than the standard set.
Packing, MOQ and Lead Time
Ask for a price on one lever apparatus for demonstrations or on several for student groups. Every quotation lists packing, delivery time and price for the number requested, and other mechanics lab equipment in India from our range, such as pulleys or a moments disc, can be priced alongside it.
Science Lab Supplies is a registered exporter with an Importer-Exporter Code and can ship to buyers in Nepal, Bangladesh, Zambia, Rwanda, South Africa and Qatar. The business is registered under Udyam as a manufacturing enterprise (UDYAM-HR-01-0014546) and for GST (GSTIN 06ADEPJ0574F2ZU).

Frequently Asked Questions
Can the Lever Apparatus show all three classes of lever?
Yes. With the pivot fitted at the centre or off-centre and masses hung in different holes, students can arrange first-, second- and third-class levers and compare the effort each needs.
Are masses included with the apparatus?
Yes. A set of calibrated masses comes with the lever, along with a heavy-duty fixing screw, so a class can begin moment experiments without buying separate weights.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the maker. The lever is built in the company's own factory at Saha, Ambala, India, and prices, packing and dispatch are arranged by the factory team rather than a reseller.
How long is the lever?
The lever measures 100 cm, which gives clear distances from the pivot for moment calculations, and the additional holes along it let students hang loads at several different positions.
