Centre of Gravity Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-ELA-5268
Jlab Export is a leading Centre of Gravity Apparatus Manufacturer,and suppliers in India
Centre of Gravity Apparatus (code EL-ELA-5268) is a simple, economical apparatus for demonstrating the geometrical centre of gravity of two-dimensional objects in school and college physics. It comprises a clear Perspex rod mounted on a base with a suspension screw at the top, and four clear acrylic laminas — one each circular, triangular, square and trapezoidal — with suspension holes around their edges. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Centre of Gravity Sets?
| Item | Listed contents |
|---|---|
| This apparatus (EL-ELA-5268) | Clear Perspex rod on a base with suspension screw; four clear acrylic laminas (circular, triangular, square, trapezoidal) with edge holes |
| Centre of Gravity Apparatus (other listing) | Parts not itemised; listed for demonstrating the centre of gravity of flat shapes by suspension |
| Set of Flat Plates to Determine Gravity Centre | Thin aluminium sheets of different shapes with a hanging plumb line |
Choose this apparatus for a self-contained stand with four clear laminas of regular shapes; the aluminium plate set includes a plumb line.
What Is the Centre of Gravity Apparatus Used For?
The apparatus turns the suspension method into a quick bench practical. Hang a lamina from the suspension screw through one of its edge holes and let it come to rest; hang a plumb line from the same point and mark the vertical line on the lamina with a washable marker. Repeat from a second hole, and the point where the two lines cross is the centre of gravity — a third line through it confirms the result, and the lamina will balance on a pencil tip at that point. Students can then check the answer against geometry: the centre of the circle, the crossing of the square’s diagonals, the meeting point of the triangle’s medians, and, for the trapezium, a point on the line joining the midpoints of the parallel sides, nearer the longer side.
The experiment supports the centre of gravity and centre of mass topics in class 11 physics and earlier lessons on stability and balance, and it is a staple of mechanics lab equipment for school physics. Clean marker lines off with a damp cloth, avoid solvents such as acetone, which can craze acrylic, and store the laminas flat so their surfaces stay unscratched.
What to Specify When Ordering
- Quantity — the minimum order is 10 units; one apparatus per student group is common for practical classes.
- Plumb line — it is not mentioned in this listing, so add a plumb line to the enquiry if you need one.
Frequently Asked Questions
Which lamina shapes are included?
Four clear acrylic laminas: one circular, one triangular, one square and one trapezoidal, each with suspension holes around its edge.
How is the centre of gravity found with this apparatus?
By suspension: mark the vertical line through the suspension point for 2 or more holes; the lines intersect at the centre of gravity.
Is a plumb line included?
The listing names the rod, base, suspension screw and four laminas only. JLab lists a brass plumb line level separately, linked below.
How does it differ from the other Centre of Gravity Apparatus listing?
This listing itemises its parts — the Perspex stand and four acrylic laminas. The other listing does not, so ask JLab to compare the two if you are choosing between them.
What is needed for an export quotation?
The quantity, destination country and port or city, delivery terms such as FOB or CIF, any packing or labelling requirements and, for tenders, the tender reference.
Who manufactures this apparatus?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a physics lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The apparatus is built at JLab’s own works rather than bought from a trader, so schools, colleges, dealers and importers order it factory-direct, every set is checked by eye before packing, and repeat orders are handled by the maker. Its CIN is U29309HR2017PTC069123, and it holds MSME Udyam registration UDYAM-HR-01-0003849 (manufacturing enterprise). JLab exports worldwide and ships to buyers in every region — for example Hong Kong in East Asia, Ireland in Western Europe, Jordan in the Middle East, Slovenia in Southern Europe and Ukraine in Eastern Europe.
