Thermal Insulation Apparatus
Product Code : LSK-PL-10293
Thermal Insulation Apparatus (SKU LSK-PL-10293) lets students measure how much energy insulation saves, using a thermostatically controlled hot plate and layers of felt or a double-glazing panel. Physics and general science teachers use it for heat-transfer and energy-saving practicals from lower secondary to college level. It is built by Science Lab Supplies at its factory on Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and is sold straight to schools, colleges, tender contractors and distributors.
Specifications
The unit is a compact 220 x 110 x 80 mm apparatus with a thermostatically controlled hot plate and provision for monitoring the input power to its electric heaters. Six felt pads and an air-cell double-glazing panel change the insulation. It connects through standard 4 mm leads and runs from a 12 V d.c., 3 A supply.

Applications and Experiments for the Thermal Insulation Apparatus
Students add felt pads one at a time, or fit the double-glazing panel, and time how long the thermostat keeps the heater on and off. Longer off periods mean less energy is needed, which ties the practical to the real question of insulating homes.
- Lower secondary science: good and poor conductors of heat and why houses are insulated.
- Class 11 physics: heat transfer by conduction and the effect of thickness on heat loss.
- Energy topics: comparing electrical energy input with and without insulation.
The hot plate becomes hot in use, so students should work under supervision and let it cool before changing pads.
Standard Scope of Supply
The apparatus comes with its thermostatically controlled hot plate, six felt pads and the air-cell double-glazing panel. The temperature probe is not included. A 12 V d.c., 3 A smoothed or regulated supply and 4 mm leads are needed to run it and can be added to the quotation if your lab lacks them.
Packing, MOQ and Lead Time
Ask for one unit for a demonstration bench or several for group practicals; the quotation will state packing, delivery time and price for the quantity you give. A power supply, leads or a stopwatch can sit on the same quotation when you price school physics lab equipment in India for a lab.
Because Science Lab Supplies is a registered exporter with an Importer-Exporter Code, it can ship to buyers in Peru, Egypt, Iraq, Nigeria, Kenya and Ghana. Send your requirement from the contact page or the enquiry cart; tender buyers can also use the lab tender page.
Frequently Asked Questions
Do I need a datalogger?
No. The apparatus has provision for datalogger monitoring of all variables, but a simple stopwatch is enough to time the heater's on and off periods.
What power supply does it need?
It needs a 12 V d.c. supply rated at 3 A, either smoothed or regulated, connected with standard 4 mm leads.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer of this apparatus. It is produced in the company's Saha, Ambala factory in India, which prepares every quotation itself.
How is the thickness of insulation varied?
Six felt pads are supplied, so students can stack one, two or more pads to see how extra thickness changes the heater's cycle.
