Demonstrative Plan Condenser/Capacitor (Product Code: SCL2405/032) is a large parallel-plate capacitor used to demonstrate how plate separation changes stored charge and capacitance in secondary-school and college electrostatics lessons. Two 250 mm metal discs stand on an insulated stand and can be moved coaxially from 160 mm apart down to touching, so a whole class can watch the gap change. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

The classic lesson connects the two discs to an electroscope, charges them, and then slowly widens the gap. Because the charge on the plates cannot escape, the electroscope leaves open further as the plates move apart: the same charge now sits at a higher potential difference, which shows students that capacitance falls as separation grows. Closing the gap again brings the leaves back down, and sliding an insulating sheet between the discs at a fixed spacing introduces the idea of a dielectric in the same period.
For clean results, set the discs parallel before charging, keep hands away from the plate faces during readings, and run the demonstration on a dry day, since humid air bleeds charge away. The large 250 mm plates keep the effect visible from the back of a classroom, making this a useful physics demonstration kit for India's senior secondary syllabus.
Jain Scientific Equipments Private Limited, which sells under the ScienceLab name, is the OEM (original equipment manufacturer) of this plate capacitor and produces it at its own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges, dealers and importers receive it factory-direct instead of through a trader, and the maker itself handles quotations, repeat orders and any replacement-part request — ask us.

How large are the plates?
Each disc of the Demonstrative Plan Condenser/Capacitor is 250 mm in diameter. The plate material is listed as solid castings, stainless steel or corrosion-resistant steel, so tell us if your tender specifies one of these.
How far apart can the plates be set?
The plates of the Demonstrative Plan Condenser/Capacitor can be spaced from 0 to 160 mm, with plate adjustment possible between 0 and 20 mm. The support lets the discs approach each other coaxially until the gap is zero.
Is an electroscope or power source included?
No electroscope or voltage source is listed with the Demonstrative Plan Condenser/Capacitor. An electroscope is normally needed to see the effect of changing the gap; ask us to quote one, and a charging source, together with the capacitor.
Can dielectric sheets be used with it?
Yes. An insulating sheet placed between the discs of the Demonstrative Plan Condenser/Capacitor shows how a dielectric changes capacitance. Dielectric sheets are not listed as part of this item, so ask us about suitable options.
Who manufactures the Demonstrative Plan Condenser/Capacitor?
The Demonstrative Plan Condenser/Capacitor is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Quotations and repeat orders for schools and distributors are handled by the manufacturer itself.
Is test documentation available?
The Demonstrative Plan Condenser/Capacitor is a qualitative demonstration apparatus, so no calibration document is listed with it. If your institution needs any test documentation, discuss it with us through the contact page before you place the order.
What should an institutional quotation request include?
For a Demonstrative Plan Condenser/Capacitor quotation, send the product code SCL2405/032, the quantity, delivery location and any tender specification. We handle single-school orders and bulk supply within India and to international markets.
To order the Demonstrative Plan Condenser/Capacitor with a quotation straight from the manufacturer, send your requirements through our contact page or add it to the enquiry cart with the rest of your physics list.
