Apparatus for Demonstrating the Change of Aggregate States of Matter
Product Code : SCL-PL-11815
Apparatus for Demonstrating the Change of Aggregate States of Matter (SKU SCL-PL-11815) is a stand-mounted set with temperature sensors for following a substance as it melts, boils or solidifies, and for showing that temperature stays steady while the state changes. It suits Class 9 science and Class 11 physics lessons on heat. Science Lab Supplies manufactures the set in Saha, Ambala, India, at Plot 448, HSIIDC Industrial Area, and deals with schools, colleges, tender contractors and distributors directly from there.
Specifications
Sensors, supports and glassware of the change-of-state set occupy one row each in the table. In short, a vertical stand and a tripod with triangular base hold air temperature sensors reading −30 to +135 °C at 0.1 °C resolution, with five clips, a 500 ml glass beaker, five light bulbs and a demonstration table on changes of state.

Applications and Experiments for the Change of States Apparatus
The apparatus is used to record temperature against time while a substance changes state, producing heating and cooling curves with flat sections at the melting and boiling points. These plateaus introduce latent heat, making the set practical heat and thermodynamics lab equipment for schools and colleges.
- NCERT Class 9 science (Matter in Our Surroundings): melting point, boiling point and latent heat, with the beaker warmed on an Electric Hot Plate.
- NCERT Class 11 physics (Thermal Properties of Matter): change of state and latent heat.
- Plotting heating and cooling curves from sensor readings at 0.1 °C resolution, and comparing them with readings from the Thermometer Set.
- Middle-school science: solids, liquids and gases and how heating changes them.
Hot liquids and glassware are involved, so students should work under supervision and let the beaker cool before handling.
Standard Scope of Supply
Each set comprises the vertical stand, the air temperature sensors (−30 to +135 °C, 0.1 °C resolution), five clips, a 500 ml glass beaker, five light bulbs, the tripod with triangular base and the demonstration table. The substances to be melted or boiled are the teacher's choice for each lesson.
Packing, MOQ and Lead Time
Science Lab Supplies can quote for one set or for enough to equip every heat practical bench; the quotation states packing, delivery time and price for that quantity. Related heat apparatus can be added to it.
Backed by an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Kenya, Ghana, Ethiopia, Tanzania, Uganda and the UAE. To have change-of-state sets priced, send the number required from the contact page or add the set to the enquiry cart; the lab tender page applies when a tender governs the order.
Frequently Asked Questions
What temperature range do the sensors cover?
The air temperature sensors read from −30 °C to +135 °C with a resolution of 0.1 °C, which covers the melting of ice and the boiling of water.
What does the apparatus demonstrate?
It shows how a substance changes between solid, liquid and gas, and that temperature holds steady during melting or boiling while latent heat is absorbed.
Is Science Lab Supplies the manufacturer or a trader?
Sets of this kind are made in the Science Lab Supplies works at Saha, Ambala, India; the company is their manufacturer, and quotations are sent by it directly.
Can the set be quoted for a school tender?
Yes. Send the quantity, delivery location and tender specification for an item-wise quotation built on the contents listed above, together with any other heat apparatus in the tender.
