Product Code : EL-SLE-4572
Jlab Export is a leading Gold Leaf Electroscope Manufacturer,and suppliers in India
Gold Leaf Electroscope (code EL-SLE-4572) is a rectangular, standard-size instrument for detecting static electricity and indicating voltage in physics labs. A thin gold leaf is secured to a narrow metal plate joined to a metal disc, and a glass front keeps air currents off the leaf while students watch it move. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Electroscopes?
| Model | Housing | Indicator | Other listed details |
|---|---|---|---|
| This electroscope (EL-SLE-4572) | Rectangular, standard size, glass front | Gold leaf on a narrow metal plate | Metal disc joined to the plate |
| Gold Leaf Electroscope (cast metal case) | Rectangular cast metal case; polythene insulated lid with finger flap | Gold leaf on a support plate, with a scale to show deflection | Fitted with socket; front glass window slides up to admit ionising material |
| Gold Leaf Electroscope (sheet metal case) | Rectangular sheet metal case on an insulated base | Gold leaf | Removable front and back sliding glass panels, one clear and one ground; removable disc electrode |
| Electroscope (needle type) | As listed on its page | Aluminium needle pivoting on an axle | Charge applied to a disc at the top |
Choose this model for everyday classroom work on charging by friction and induction. The cast-case model adds a deflection scale and a sliding window for ionising material, the sheet-metal model has clear and ground glass panels and a removable disc electrode, and the needle electroscope uses a pivoting aluminium needle in place of a leaf.
What Is the Gold Leaf Electroscope Used For?
A gold leaf electroscope shows whether a body carries static charge. When a charged rod is brought near the disc, charge is induced on the plate and the leaf, and because like charges repel, the leaf lifts away from the plate; touching the disc with the rod charges the instrument by conduction, so the leaf stays apart after the rod is removed. The higher the potential, the wider the leaf opens, which is why the instrument can indicate voltage as well as detect charge. It is standard physics lab equipment for schools in India, used in practicals on charging by rubbing and induction and in the electrostatics chapter of class 12 physics.
To test the sign of an unknown charge, first charge the electroscope from a rod of known charge, then bring the unknown body near the disc: the leaf opens wider for a like charge and falls back for an unlike one. Touch the disc with a finger to earth it before the next run. Work in a dry room, because damp air lets the charge leak away, and handle the instrument gently — gold leaf is extremely thin and tears easily, which is also why the glass front stays closed during use.
What to Specify When Ordering
- Quantity — the minimum order is 10 electroscopes; many labs plan one per demonstration bench or student group.
- Any extra features you need, such as a deflection scale or an earthing terminal — these are not listed for this model, so state them and JLab will confirm what it can supply.
- Charging accessories — friction rods, silk and fur can be added to the same enquiry.
- Delivery details — destination, and a tender reference if the order is for a tender.
Frequently Asked Questions
What does a gold leaf electroscope do?
It detects static charge. Charge reaching the disc spreads to the metal plate and the gold leaf, and the leaf moves away from the plate because like charges repel; the size of the movement gives a rough idea of how high the potential is.
Can this electroscope measure voltage?
It indicates voltage comparatively: the leaf opens further as the potential rises. No scale is listed for this model, so readings are by eye. If you need a scale, the cast-case gold leaf electroscope linked above is listed with one.
Why does the electroscope have a glass front?
The glass front stops air currents from moving the very light gold leaf, so any movement you see is caused by charge, while still letting students watch the leaf closely.
How can students tell a positive charge from a negative one?
Charge the electroscope first from a rod of known charge, for example a glass rod rubbed with silk. Then bring the test body near the disc: wider divergence means the same sign, reduced divergence means the opposite sign.
Are friction rods and cloths included?
They are not part of this listing, which covers the electroscope. JLab lists a friction rod kit with glass and ebonite rods, silk cloth and a faux fur pad separately, and it can be added to the same enquiry.
What information is needed for an export quotation?
Send the quantity, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), any packing or labelling needs, and the tender reference if one applies.
Who manufactures this electroscope?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of physics lab instruments and other science education equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This electroscope is built at JLab’s own works, not bought from a trader, so schools, colleges, dealers and importers deal factory-direct; every unit is visually inspected before dispatch, and repeat orders come from the same manufacturer. The company is registered under CIN U29309HR2017PTC069123 and holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise. Buyers in every region are served through JLab’s worldwide exports — for example in Angola in Central Africa, Burkina Faso in West Africa, Estonia in Northern Europe, Botswana in Southern Africa and Mexico in North America. For tender enquiries see the JLab lab tenders page.
