Electrophorus Strip Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-4545
Jlab Export is a leading Electrophorus Strip Manufacturer,and suppliers in India
Electrophorus Strip (code EL-SLE-4545) is a simple electrostatics device that yields small amounts of static charge for classroom experiments. It pairs an insulating bakelite disc with a brass disc mounted on an insulating handle, and a small conducting sphere on the brass disc lets students earth it during the charging sequence. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Electrophorus Models?
| Model | Insulating base | Metal disc and handle | Other listed details |
|---|---|---|---|
| Electrophorus Strip (EL-SLE-4545) | Bakelite disc | Brass disc on an insulating handle | Small conducting sphere for earthing |
| Electrophorus Brass N.P. | Thick ebonite base | Brass disc with knob and ebonite handle | Listed for demonstrating electrostatic induction |
| Electrophorus | Plastic base | Metal disc, 18 cm, clear acrylic handle | Rubbing cloth included |
The Electrophorus Strip is the straightforward bakelite-and-brass version with its own earthing sphere. If you want a rubbing cloth in the box, the plastic-base Electrophorus lists one; the ebonite-base model is the alternative where an ebonite insulator is specified.
How Is the Electrophorus Used?
An electrophorus charges by induction, not by contact. Rub the bakelite disc with fur or a woollen cloth so it carries a static charge, then lower the brass disc onto it by the insulating handle. The charge on the bakelite pulls opposite charge to the near face of the brass and pushes like charge to the far side; touching the conducting sphere briefly with a finger earths the brass and lets that like charge escape. Lift the brass disc by its handle and it now carries a charge opposite to the bakelite’s, ready to show a small spark to a knuckle, diverge the leaves of a gold leaf electroscope, or build up charge in a Leyden jar. Because the bakelite gives up very little of its own charge, the brass disc can be recharged several times from one rubbing. The device fits class 8 lessons on static charges and the electroscope and the class 12 topic of charging by induction — a simple, reusable piece of physics lab equipment for schools.
Static experiments work far better in dry weather; humid air lets charge leak away, so warm and dry the bakelite before class if results are weak. Hold the brass disc only by the handle, keep the bakelite surface clean and free of grease, and store the two discs apart.
What to Specify When Ordering
- Quantity — the minimum order is 10 units, for example one per bench group.
- Rubbing material — fur or a woollen cloth is not listed as included, so add one or ask JLab.
- Detectors — a gold leaf electroscope or Leyden jar to show what the electrophorus can do.
Frequently Asked Questions
What is the Electrophorus Strip used for?
To produce small, repeatable amounts of static charge for electrostatics experiments, such as charging an electroscope or a Leyden jar and showing charging by induction.
What is the small sphere on the brass disc for?
Earthing. During charging you touch the sphere briefly while the brass disc rests on the charged bakelite, which lets the repelled charge flow away and leaves the disc charged by induction.
Do I need to rub the bakelite disc before every charge?
Usually not. The bakelite keeps most of its charge, so the brass disc can be charged several times from one rubbing; in humid weather the charge fades faster and the disc needs rubbing again.
Is a rubbing cloth or fur included?
The listing describes the bakelite disc, the brass disc with handle and the earthing sphere only. Ask JLab to add a suitable rubbing material if you need one.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an electrostatics, electricity and general science apparatus manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The electrophorus is put together at JLab’s own works, not bought in from a trader, so schools, colleges, dealers and importers order it factory-direct; each one is visually inspected before dispatch, and repeat orders are handled by the maker. JLab exports worldwide and can serve buyers in any region, from Finland in Northern Europe, Tajikistan in Central Asia and Moldova in Eastern Europe to Sudan in North Africa and New Zealand in Oceania. Tender details are on the JLab lab tenders page.
