Gold Leaf Electroscope
Gold Leaf Electroscope (Product Code: SCL-335/066) is an electrostatics instrument used to detect electric charge and compare its size in school and college physics laboratories. Its leaf hangs in a sheet metal case with sliding glass panels, and an internal acrylic scale graduated 0–90° lets students read the deflection. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as part of its school physics lab equipment range.
Specifications

| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
What Is the Gold Leaf Electroscope Used For?
Touching the disc with a charged rod spreads charge to the blade and leaf, which repel each other so the leaf swings out; the angle read on the 0–90° scale shows how much charge is present. Students use it to show charging by contact and by induction, to find the sign of an unknown charge, and to compare how well different materials conduct or insulate.
Sliding the clear front panel up lets a teacher place ionising material inside the chamber to show that ionised air discharges the leaf. Work in dry conditions, earth the case through the side terminal between trials, and handle the leaf gently, since it is extremely thin.
What to Specify When Ordering
- Number of electroscopes needed for demonstration and student benches.
- Whether spare leaves are required in addition to the one pair supplied.
- Charging accessories, such as rods and rubbing cloths, to be quoted with it.
OEM Manufacturer
Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM behind this gold leaf electroscope and produces it at its own licensed factory at Saha, Ambala, Haryana, India. The company is incorporated under CIN U29309HR2020PTC087597, and its Saha works operates under Factory Licence AMB-ONLINE-CHD-J-414. Schools, colleges and importers receive quotations straight from the manufacturer, and replacement leaves can be requested from it directly. More details are on the company profile.
Related Physics Lab Equipment
An electroscope needs charged objects to test. These items are used with it in electrostatics lessons:
- Ebonite Rod — rubbed with fur or wool to give a negative charge.
- Friction Rod, Glass/Brass, 300mm — for comparing charging of an insulator and a conductor.
- Friction Cloth, Cotton — a rubbing cloth for charging rods.
- Electroscope, Needle — an alternative detector type for comparison.
More electricity and electrostatics apparatus is listed in the Physics Lab category.
Frequently Asked Questions
What is included with the Gold Leaf Electroscope?
The Gold Leaf Electroscope is supplied complete with one pair of leaves, fitted in a rectangular sheet metal case with a removable disc electrode, sliding clear and ground glass panels, and an internal 0–90° acrylic scale. Charging rods and cloths are separate items.
How does the Gold Leaf Electroscope reduce charge leakage?
In the Gold Leaf Electroscope, the disc electrode passes through a moulded plastic bush that insulates it from the metal body, preventing charge leakage. The whole case also sits on an insulated base, helping the leaf hold its deflection long enough for readings.
What is the scale range of the Gold Leaf Electroscope?
The Gold Leaf Electroscope has a clear acrylic circular scale inside the chamber graduated from 0 to 90 degrees. Reading the leaf deflection against this scale lets students compare charges instead of only detecting them.
Can the leaves of the electroscope be replaced?
Yes. On the Gold Leaf Electroscope, the clear front panel slides up so a leaf can be fixed to the plated metal blade under the plastic bush. One pair of leaves is supplied; ask us about additional leaves when you request a quotation.
Who manufactures the Gold Leaf Electroscope?
The Gold Leaf Electroscope is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM, at its licensed factory in Saha, Ambala, Haryana, India. Buyers deal directly with the maker for quotations, replacement leaves and repeat supply to schools, colleges and dealers.
Why does the Gold Leaf Electroscope have an earthing terminal?
The side terminal on the Gold Leaf Electroscope connects the case to earth. Earthing gives a stable reference, lets students discharge the instrument quickly between trials, and is needed when demonstrating charging by induction.
