Heat Receiver / Leslie-Type Receiver
Product Code : SCL-PL-12382
Heat Receiver / Leslie-Type Receiver (SKU SCL-PL-12382) is a hollow 80 mm cylinder with one black side and one polished silver side, used to compare how surfaces emit and absorb radiant heat in school and introductory college physics. Science Lab Supplies manufactures the receiver at its Plot 448 factory in the HSIIDC Industrial Area, Saha, Ambala, India, and sells it directly to schools, colleges, tender contractors and distributors.
Specifications
The receiver is a hollow cylinder 80 mm across. One side is black and the opposite side is silver-coloured and polished, so both finishes can be compared under identical conditions. A top opening with a stopper or lid takes hot or boiling water, and a silicone tube is fitted.

Applications and Experiments for the Heat Receiver
The receiver shows that a dull black surface radiates and absorbs heat more readily than a polished silver one. Filled with hot water, it lets students compare the two faces with thermometers or heat sensors, making it simple heat and thermodynamics lab equipment for schools and colleges.
- Class 7 science: heat transfer by radiation from dark and light surfaces.
- Class 11 physics: emission and absorption of thermal radiation.
- Comparing cooling from the black and polished faces with thermometers at equal distances.
Standard Scope of Supply
The Heat Receiver / Leslie-Type Receiver is supplied as a single unit: the hollow 80 mm cylinder with black and polished silver sides, the stopper or lid, and the silicone tube. Thermometers, radiation sensors and a source of hot water are separate items that the laboratory provides.
Packing, MOQ and Lead Time
Quotations can cover one receiver for a demonstration bench or several for a class that works in small groups. Each quotation lists the packing, delivery time and price for the quantity you name, and other school physics lab equipment can be priced on the same document.
Holding an Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Malaysia, Peru, Egypt, Iraq, Nigeria and Kenya. To ask for a price, write through the contact page, add the item to the enquiry cart, or check the lab tender page for institutional purchases.
Frequently Asked Questions
What does the Leslie-type receiver demonstrate?
It shows that surface finish affects radiant heat transfer: with hot water inside, the black side emits more heat radiation than the polished silver side, which thermometers or sensors at equal distances can detect.
What size is the Heat Receiver / Leslie-Type Receiver?
The receiver is a hollow cylinder 80 mm in diameter, with a top opening closed by a stopper or lid through which it is filled with hot or boiling water before each experiment.
Is Science Lab Supplies the manufacturer or a trader?
It is the manufacturer. The receiver is produced in the company’s own factory in Saha, Ambala, India, so schools and contractors deal with the maker directly and receive factory quotations.
Is the receiver safe for student use?
It holds hot or boiling water, so there is a scald risk when filling and handling it. A teacher should fill the vessel, and students should take their readings without touching the hot surfaces.
