Electroscope, Gold Leaf
Electroscope, Gold Leaf (Product Code: SLE/PHY/167) is a metal-cased electrostatic instrument used to detect charge and compare its size in secondary school and college physics labs. A single gold leaf attaches to a metal plate held on an insulating bush, and a scale lets students measure how far the leaf deflects. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM, at its own factory in Ambala, India, as part of its range of physics lab instruments.

What Is the Gold Leaf Electroscope Used For?
With its scale, this electroscope takes students beyond a yes-or-no answer: they can compare deflections when a rod is rubbed with different cloths, watch the leaf fall as charge leaks away, and record the results in a table. The earthing terminal takes a 4 mm lead, so the case can be earthed whenever an experiment calls for it, and the instrument works well alongside Faraday's pails for charge-distribution studies.
Charging by induction is a classic exercise: hold a charged rod near the plate, touch the plate briefly to earth, remove the earth connection and then the rod, and the leaf stays deflected with the opposite charge. Store the electroscope in a dry cupboard, because moisture on the insulating bush lets charge leak away and shortens readings.
What to Specify When Ordering
- The number of instruments for demonstration or group practicals.
- The quantity of replacement gold leaves, which are supplied separately.
- 4 mm earthing leads, if your lab does not already stock them.
- Charging accessories such as friction rods, cloths or a proof plane.
OEM Manufacturer
ScienceLab is the trading name of Jain Scientific Equipments Private Limited, which manufactures this gold leaf electroscope as the OEM at its own licensed factory in Saha, Ambala, Haryana. Buying from the maker means spare leaves and repeat orders are discussed with the same company that produces the instrument. Institutional and tender buyers who need vendor registration details can note GSTIN 06AAECJ8618A1ZT and LEI 3358004HRD1JIVXKYX49. Learn more on our company profile.

Frequently Asked Questions
What does the scale on the Electroscope, Gold Leaf do?
The scale on the Electroscope, Gold Leaf lets students measure the deflection of the leaf, so they can compare charges and record how quickly charge leaks away instead of only noting whether the leaf moved.
How is the Electroscope, Gold Leaf earthed?
The Electroscope, Gold Leaf has a 4 mm socket earthing terminal on its metal case. Connect a 4 mm lead from this socket to an earth point when an experiment, such as charging by induction, requires the case to be earthed.
Can a damaged gold leaf be replaced?
Yes. The Electroscope, Gold Leaf uses a metal plate to which a single gold leaf may be attached, and replacement gold leaves are available separately, so a torn leaf can be renewed without buying a new instrument.
Who manufactures the Electroscope, Gold Leaf?
The Electroscope, Gold Leaf is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer based in Ambala, Haryana, India. It is produced at the company's own factory and supplied factory-direct to institutions, dealers and importers.
Is a calibration certificate supplied with the Electroscope, Gold Leaf?
No calibration certificate is listed for the Electroscope, Gold Leaf, whose scale is intended for comparing leaf deflections in teaching. If a tender requires a certificate or test document, please raise it with us through the contact page before ordering.
What details should I send for a quotation?
For the Electroscope, Gold Leaf, send product code SLE/PHY/167, the quantity, the number of spare gold leaves and your delivery location in India or international markets. We then quote directly as the manufacturer.
