Pith Ball on Stand Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-4680
Jlab Export is a leading Pith Ball on Stand Manufacturer,and suppliers in India
Pith Ball on Stand (code EL-SLE-4680) is an electrostatics apparatus in which two light balls hang on nylon thread from a hook on a stand, used to show the attraction and repulsion of electric charges in school and college physics lessons. When the balls are charged or a charged rod is brought near, their movement makes the forces between charges easy to see. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Pith Ball Apparatus?
| Model | Stand | Balls and thread |
|---|---|---|
| This Pith Ball on Stand (EL-SLE-4680) | Stand with a hook | Two balls on nylon thread |
| Electroscope Pith Ball | Insulated stand on a solid round base, with hook | Silk thread with a pith ball at each end; supplied with 3 strings and six 8 mm pith balls |
| Pith Ball Electroscope | Chrome-plated brass pillar on a wooden base | 2 pith balls on unspun silk |
All three demonstrate the same effect. Choose the electroscope pith ball set when you want spare strings and balls in the pack, the brass-pillar model for a wooden-base stand, and this apparatus for a simple two-ball stand on nylon thread.
What Is the Pith Ball on Stand Used For?
It shows that like charges repel and unlike charges attract. Rub a glass rod with silk or an ebonite rod with fur and touch it to both balls: they take the same kind of charge and swing apart. Bring the charged rod near an uncharged ball and it is first attracted; charge one ball from the glass rod and the other from the ebonite rod and they pull together. These demonstrations support middle-school lessons on charging by rubbing and the class 12 electrostatics chapter.
Static experiments are more reliable in dry air, because moisture lets the charge leak away. Wipe the rods dry, keep hands off the balls once they are charged, and discharge the balls by touching them with a finger between demonstrations. Store the apparatus with the thread untangled so the balls hang freely.
What to Specify When Ordering
- Quantity — the minimum order is 10 units; schools often order one per bench for group work.
- Friction rods — add glass and ebonite rods (with silk and fur) if you need complete electrostatics sets.
- Dimensions — if a tender specifies ball size or stand height, include it so JLab can confirm.
Frequently Asked Questions
What does the pith ball on stand demonstrate?
The attraction and repulsion of electric charges. Balls with the same charge move apart, while oppositely charged balls, or a charged rod and an uncharged ball, move together.
How many balls are there, and what are they hung on?
Two balls, suspended on nylon thread that is attached to a hook on the stand.
Why do the balls stop responding on a humid day?
Moisture in the air and on surfaces lets charge leak away quickly. Work in a dry room, dry the rods before rubbing, and repeat the charging if the balls fall back together.
Are friction rods included?
They are not part of this listing. Glass and ebonite friction rods are separate JLab items, linked below, and can be ordered with the apparatus.
What information is needed for an export quotation?
Send the quantity, the destination country and port or city, your preferred delivery terms (for example FOB or CIF), any packing or labelling requirements, and the tender reference if the order is for a tender.
Who manufactures this apparatus?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and quotes for it directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an electricity and physics demonstration apparatus manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This apparatus is built at JLab’s own works and not bought from a trader, so schools, colleges, dealers and importers buy factory-direct, each unit is visually inspected before dispatch, and spare threads and repeat orders come from the manufacturer. The company holds CIN U29309HR2017PTC069123 and MSME Udyam registration UDYAM-HR-01-0003849 (manufacturing enterprise). JLab exports worldwide and ships to buyers in every region — for example Mexico in North America, Colombia in South America, Hong Kong in East Asia, Bhutan in South Asia and the UK in Western Europe. Tender information is on the JLab lab tenders page.
