Conductivity Demonstrator (Product Code: SLE/CH/99) is a simple classroom apparatus that shows at a glance whether a liquid conducts electricity. Two platinum electrodes are mounted on a non-conductive support together with a light globe and terminals; connected to a power source and dipped into a solution, the globe glows when the liquid carries a current and stays dark when it does not. Science and chemistry teachers in middle and secondary schools use it to separate electrolytes from non-electrolytes in front of the whole class. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a school laboratory equipment supplier in India.
| Parameter | Detail |
|---|---|
| Electrodes | Two platinum electrodes |
| Mounting | Non-conductive support |
| Indicator | Light globe |
| Connections | Terminals for attaching the power supply |
| Power source | Battery pack or 6V power supply |
Connect the terminals to a battery pack or 6V power supply, then lower the electrodes into a beaker of the test liquid. Salt solution or dilute acid lights the globe, while distilled water or sugar solution leaves it dark, which gives students a clear, visual contrast between ionic and molecular substances. Comparing the brightness across several solutions also opens a discussion of strong and weak electrolytes.
Rinse the electrodes in distilled water and blot them dry between samples so one solution does not contaminate the next, and disconnect the power before changing beakers. Platinum is chosen for the electrodes because it resists attack by the acids and salt solutions being tested. A chemistry lab instruments supplier can quote the demonstrator together with beakers and leads so the activity is ready to run.
The Conductivity Demonstrator comes from Jain Scientific Equipments Private Limited, which operates under the ScienceLab name in Ambala, Haryana, India, producing science teaching apparatus. See our company profile for more about the business.

What does the Conductivity Demonstrator show?
Whether a solution conducts electricity: the light globe glows for conducting liquids and stays off for non-conducting ones.
What power source does it need?
A battery pack or a 6V power supply connected to its terminals. If you want a supply quoted with it, mention this in your enquiry.
Why are the electrodes platinum?
Platinum is highly resistant to corrosion, so the electrodes stay clean and consistent when dipped into acids, bases and salt solutions.
Does it give a numerical conductivity reading?
No. It is a qualitative demonstrator; quantitative work needs a conductivity meter.
How should the electrodes be cleaned?
Rinse them in distilled water after each solution and dry gently. Do not scrape the platinum surfaces.
Is a replacement globe available?
Spare-part availability is not listed here; please ask through our contact page.
Can you quote for several schools at once?
Yes. Share the quantity for each delivery point and we will prepare a consolidated quotation for India or international delivery.
