Newton’s Law of Cooling Manufacturer,Supplier and Exporter in India
Product Code : SCL-EAE-11213
The Newton’s Law of Cooling apparatus manufactured by Lab Exports is a high-accuracy instructional kit engineered to validate fundamental thermodynamic principles. The unit features a dual-wall design comprising an internal copper calorimeter nested inside a larger outer copper container. This dual-wall configuration creates a stable, enclosed air jacket that isolates the inner container from erratic external drafts, ensuring uniform environmental boundaries for scientific calculations.
Built for long-term reliability in busy educational environments, all metal components are constructed from corrosion-resistant, high-grade copper and brass. The top lid features pre-drilled rubber stoppers that secure a laboratory thermometer and a manual wire stirrer. By minimizing manual measurement errors, this system acts as an indispensable resource for educators updating their physics lab equipment inventory with standard-compliant school education kits.
Key Features
Concentric Dual-Wall Isolation: Eliminates external convective drafts to maintain a controlled testing environment.
High-Thermal-Conductivity Copper: Maximizes rapid, accurate heat transfer response within the internal vessel.
Integrated Manual Stirrer: Features a built-in brass wire loop to ensure uniform liquid temperature distribution.
Precise Instrument Placement: Fitted with rubber corks to hold thermometers securely without glass-to-metal contact.
Robust Leak-Proof Sealing: Machined component lids prevent unintended evaporative cooling losses.
High Durability Profile: Heavy-gauge metal construction resists mechanical warping under repeated high-temperature cycling.

Applications / Uses
Verifying Newton’s Law of Cooling empirically by plotting temperature versus time graphs.
Studying thermal radiation, heat convection, and convective heat transfer coefficients in physics experiments.
Utilizing as an interactive component within standard didactic models for physics and mechanical engineering coursework.
Calculating the specific heat capacity of unknown liquids by relative cooling rate comparisons.
How to Use the Newton’s Law of Cooling Apparatus
Place the outer container on a flat, vibration-free laboratory benchtop.
Fill the inner copper calorimeter vessel to roughly 80% capacity with hot water heated to approximately 80°C.
Insert the inner calorimeter carefully inside the outer jacket using the insulating spacer rings.
Place the insulated lid on top, then position the thermometer and stirrer through the designated rubber stoppers.
Agitate the water gently using the manual stirrer to maintain an even internal temperature profile.
Record the water temperature at regular time intervals (e.g., every 60 seconds) and plot the values against time to evaluate the cooling curve relative to ambient room temperature.
Safety Note: Use heat-resistant gloves when handling hot water to avoid thermal burns. Avoid striking the thermometer bulb against the copper walls of the calorimeter.
Care & Maintenance
Thoroughly drain and dry both the inner and outer copper containers after every laboratory session to prevent oxidized discoloration.
Clean all surfaces using a soft cloth and mild, non-abrasive detergent; never use steel wool or harsh chemicals.
Inspect the rubber stoppers periodically for cracking and store them away from direct sunlight.
Keep the kit inside a dry, clean cabinet alongside your other core educational laboratory instruments.

Frequently Asked Questions
What is Newton's Law of Cooling apparatus used for?
It is used in science classrooms to prove that the rate of heat loss from a body is directly proportional to the difference in temperatures between the body and its surrounding environment.
Why does this apparatus use a double-walled container?
The double-walled configuration provides an insulated air barrier that protects the inner calorimeter from external room drafts, ensuring that heat loss occurs uniformly.
What material is the inner calorimeter made of?
The inner calorimeter is constructed from high-purity copper, chosen for its excellent thermal conductivity and resistance to thermal degradation.
Are thermometers included with this testing kit?
Standard liquid-in-glass thermometers are typically sold separately or can be integrated upon request, though the kit includes the pre-drilled rubber stoppers needed to mount them [confirm].
Can this kit be used to test liquids other than water?
Yes, it can be used to study the cooling rates and thermal properties of various non-corrosive liquids, such as mineral oils or glycerin solutions.
