Pan Balance Scale Demonstration Lever
Product Code : LSK-PL-10356
Pan Balance Scale Demonstration Lever (SKU LSK-PL-10356) is a 27 cm tall lever balance with a low-friction brass pivot, a balance needle, a protractor and stainless steel pans, used to compare masses and teach torque, moments and centre of gravity. It suits mechanics lessons from middle school to Class 11. The lever, pivot and pans are put together in the Science Lab Supplies factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, which manufactures the balance and prices it directly for schools, colleges, tender contractors and distributors.

Applications and Experiments for the Pan Balance Demonstration Lever
With the pans loaded, students can watch the needle against the protractor and see how unequal loads tip the lever. It supports lessons on comparing masses, levers, moments and static equilibrium in middle-school science and the rotational-motion chapter of NCERT Class 11 physics.
- Middle-school science: comparing masses and introducing the lever as a simple machine, then weighing the same objects on a Physical Balance Brass & Wood 250 gm.
- Class 11 physics: principle of moments and conditions for equilibrium of a rigid body, with known loads from a Physical Weight Box Of 100gm Iron Chrome Plate.
- Centre-of-gravity work: using the zero offset rod to show how shifting mass changes the balance point.
- Reading the protractor to relate the tilt of the lever to the difference in load.
Standard Scope of Supply
Each apparatus includes the base, support rod, mounting hardware brackets, zero offset rod, horizontal balance lever, balance needle, protractor, pan holders and pans. Masses for loading the pans can be added as a separate line on the same quotation, so the balance is ready for use on arrival.
Packing, MOQ and Lead Time
A quotation can be prepared for one demonstration balance or a set for every bench. It shows packing, delivery time and price for that quantity, and a mass set or other mechanics apparatus can be priced alongside it on the same document.
As a registered exporter holding an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Sri Lanka, Vietnam, Malaysia, Peru, Egypt and Iraq. The business is registered under Udyam as a manufacturing enterprise (UDYAM-HR-01-0014546) and for GST (GSTIN 06ADEPJ0574F2ZU). The balances and masses you need can be listed in the enquiry cart or described on the contact page, and a school or college tender can follow the lab tender page.
Frequently Asked Questions
What parts come with the demonstration lever?
The base, support rod, mounting brackets, zero offset rod, horizontal balance lever, balance needle, protractor, pan holders and stainless steel pans of 10 cm diameter, each pan weighing 1.2 oz.
What is the pivot made of?
The lever turns on a low-friction brass pivot point, which gives more precise balance and measurement when small differences in load are compared on the protractor.
Which topics can it be used for?
Comparing masses, torque, centre of gravity, levers, moments and static forces, from simple balance activities in middle school to the principle of moments in Class 11 physics.
Is Science Lab Supplies a trader for this balance?
No. The demonstration lever is assembled from its brass pivot up at the company’s own factory in Saha, Ambala, India, and the quotation you receive is issued by that factory without a middleman.
