Conductometer, For Thermal Conductivity
Product Code : LSK-PL-10360
Conductometer, For Thermal Conductivity (SKU LSK-PL-10360) is a demonstration apparatus that compares how well brass, copper, aluminium, iron and stainless steel conduct heat. Five metal rods radiate from a brass hub, and wax in a cavity at the end of each rod melts at a different time when the hub is heated. The five-rod hub and its wooden handle are manufactured by Science Lab Supplies at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and the factory quotes schools, colleges, tender contractors and distributors with no agent in between.
Specifications
Metals, layout and handle of the five-rod conductometer take one row each. In short, rods of five metals are spaced equally around a brass hub held over a flame by a wooden handle, and each rod has a cavity at its outer end for paraffin, so the order in which the wax melts ranks the metals by conductivity.

Applications and Experiments for the Conductometer
Because all five rods are heated from the same hub, the only variable is the metal, so the melting order gives a fair visual ranking of conductivity. The demonstration fits the heat chapter of Class 7 science and the conduction topic in NCERT Class 11 physics.
- Class 7 science (CBSE/NCERT): showing that heat travels through solids by conduction and that some metals conduct faster, with a second view of warming on Heat Sensitive Paper.
- Class 11 physics: introducing thermal conductivity as a property of the material.
- Fair-test practice: identifying the controlled variables, such as one flame from a Brass Spirit Lamp 100ml, before predicting the melting order.
The method uses an open flame, hot metal and molten wax, so hold the apparatus only by its wooden handle.
Standard Scope of Supply
The conductometer is supplied as a single assembly as described above: five metal rods mounted on the brass hub with the wooden handle. Paraffin wax and a burner or spirit lamp for the demonstration can be added as separate lines on the same quotation.
Packing, MOQ and Lead Time
Quotations are available for one conductometer or a class quantity, and each lists the packing, delivery time and price for that number. Other heat apparatus, a flame source and wax can be priced on the same document so the whole demonstration arrives together.
Registered as an exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Egypt, Iraq, Nigeria, Kenya, Ghana and Ethiopia. The business is registered under Udyam as a manufacturing enterprise (UDYAM-HR-01-0014546) and for GST (GSTIN 06ADEPJ0574F2ZU). Heat-transfer apparatus can be requested through a message on the contact page or a list in the enquiry cart, and bids against a published tender go via the lab tender page.
Frequently Asked Questions
Which metals does the conductometer compare?
Brass, copper, aluminium, iron and stainless steel, one rod of each, all fixed to the same brass hub so they receive heat from a common source at the same time.
How is the demonstration carried out?
Place paraffin wax in the cavity at the end of each rod, hold the brass hub over a flame by the wooden handle, and note the order in which the wax melts on the five rods.
Is it safe for a school class?
It involves a flame, hot rods and molten wax, so it should be run by the teacher or under close supervision, with students kept clear of the heated hub.
Is Science Lab Supplies the maker of this apparatus?
Yes. Rods, brass hub and handle are made and fitted together in the company’s Saha, Ambala, India factory, so you buy from the producer rather than a trader, and that factory prepares your quotation.
