Demonstration Lever Balance
Product Code : LSK-PL-10316
Demonstration Lever Balance (SKU LSK-PL-10316) is a teacher's apparatus for showing static forces, levers and the working principle of an analytical balance. Scale pans hang from equidistant holes along a horizontal arm, and a needle and protractor show the tilt. It serves school mechanics lessons and introductory college physics. Science Lab Supplies produces this balance at its Ambala works, Plot 448, HSIIDC Industrial Area, Saha, India, as the manufacturer, and quotes schools, colleges, tender contractors and distributors directly.
Specifications
The parts of the lever balance are laid out one per row below. In short, a vertical stem on a base carries the horizontal balance arm, drilled with equidistant holes for setting the scale pans at different distances from the pivot; a zero offset rod trims the empty arm, and a balance needle reads against a protractor.

Applications and Experiments for the Demonstration Lever Balance
The lever balance lets a class watch the principle of moments at work: loads placed at different holes on each side either balance the arm or tip it, and the needle on the protractor shows the result. The same set-up explains how an equal-arm analytical balance compares masses.
- Middle-school science: levers and balancing loads, using steel masses from the Mass Set with Hangers.
- Class 11 physics: principle of moments and equilibrium of a rigid body, alongside the Center-of-Gravity Plate Set for centre of gravity.
- Explaining the equal-arm principle of an analytical balance.
Standard Scope of Supply
The apparatus comprises the vertical stem with base, the zero offset rod, the horizontal balance arm with its equidistant holes, scale pans with hooks, the balance needle and the protractor. A set of masses for loading the pans can be added to the quotation if the lab needs one.
Packing, MOQ and Lead Time
A quotation can be for one demonstration balance or several for different classrooms. It will set out the packing, delivery time and price for that number, and other mechanics lab equipment in India from the same range, such as lever or moment apparatus, can share the quotation.
Registered as an exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Egypt, Iraq, Nigeria, Kenya, Ghana and Ethiopia. The business is registered under Udyam as a manufacturing enterprise (UDYAM-HR-01-0014546) and for GST (GSTIN 06ADEPJ0574F2ZU). A mechanics department can send its balance and mass requirements from the contact page, list them in the enquiry cart, or follow the lab tender page for a tender.
Frequently Asked Questions
What can be demonstrated with this lever balance?
It is designed for demonstrating static forces, levers and an analytical balance. The equidistant holes let the load positions be varied to show when the arm balances and when it tips.
What is the zero offset rod for?
The zero offset rod is used to bring the empty arm to balance before loads are added, so the needle starts from the zero mark on the protractor and readings are fair.
Is Science Lab Supplies the manufacturer or a trader?
Demonstration balances of this design are made by Science Lab Supplies in its own Saha, Ambala factory in India; as the manufacturer, it sends the quotation and arranges dispatch without a middleman.
Does the balance come with masses?
The apparatus comes with scale pans with hooks, a balance needle and a protractor. If you need a mass set as well, ask for it on the contact page and it can be added to the quotation.
