Apparatus for Changing the Thermal Conductivity
Product Code : SCL-PL-11819
Apparatus for Changing the Thermal Conductivity (SKU SCL-PL-11819) is a thermal conductivity apparatus for comparing how well different metals conduct heat, using three rods of different metals, five alcohol thermometers and a water heater. It suits heat-transfer lessons in middle school and Class 11 physics. Manufactured by Science Lab Supplies in Saha, Ambala, India (Plot 448, HSIIDC Industrial Area), it goes straight from the factory to schools, colleges, tender contractors and distributors.
Specifications
The main unit measures 300 x 150 mm and carries three rods of different metals fitted with a movable metal ring. Glass cups, copper cans, thermometers in protective cases, a water heater and a digital stopwatch provide what is needed to heat, measure and time each run.

Applications and Experiments for the Thermal Conductivity Apparatus
Students heat one end of the rods and follow the temperature along each metal to see which conducts heat fastest. The experiment fits conduction in CBSE/NCERT Class 7 science and heat transfer in Class 11 physics, and it forms part of a school's heat and thermodynamics lab equipment.
- Class 7 science (Heat): good and poor conductors of heat.
- Class 11 physics (Thermal Properties of Matter): comparing conduction in three metals.
- Timing temperature rises with the stopwatch and plotting temperature against time.
Standard Scope of Supply
The set includes the three-rod unit with movable ring, five alcohol thermometers with five cases, five 100 ml and five 250 ml glass cups, two copper cans, four cylinders, four rubber rods, a water heater, a digital stopwatch, a pair of scissors and the experiment demonstration table.
Packing, MOQ and Lead Time
Whether you need one set for the physics teacher or several for a practical class, the quotation spells out the packing, delivery time and price for that number. Conduction rings and other heat apparatus can be priced on the same document.

Frequently Asked Questions
What does the Apparatus for Changing the Thermal Conductivity show?
It lets students compare how quickly heat travels along three rods made of different metals, so they can rank the metals as better or poorer conductors of heat.
What type of thermometers are included?
Five alcohol thermometers reading −10 to 150 °C are supplied with five cases, enough to take readings at several points along the rods at the same time.
Is Science Lab Supplies the manufacturer or a trader?
The company is the manufacturer. Its Saha, Ambala factory in India produces this apparatus, so buyers receive a quotation from the maker with no trading intermediary.
Is the experiment safe for students?
The water heater and heated rods get hot, so students should work under teacher supervision, keep the heater away from the table edge and let rods, cans and cups cool before handling.
