Reliant Lab Searles Thermal Conductivity Apparatus with 25mm Copper Rod

• Rod Material : Copper 
• Rod Size : 30 cm long
• Dia : 2.5 cm

Features

• Large 25mm Copper Specimen: Features a solid, high purity copper rod with a 25mm diameter to ensure a significant and stable heat flux for more accurate data collection.
• Copper Spiral Cooling Jacket: The cold end is wrapped in a high efficiency copper spiral through which water flows to absorb conducted heat.
• Four Point Thermometry: Includes four dedicated thermometer pockets to capture all necessary thermal variables.
• Steady State Optimization: Designed to work with a constant level water tank to achieve a thermal steady state, where heat input exactly equals heat output.

Applications

• Calculating Conductivity : The primary use is determining the absolute coefficient of thermal conductivity for copper in physics and engineering laboratories.
• Steady State Demonstrations: Used to teach the concept of thermal equilibrium in thermodynamics, where temperature gradients remain constant over time.
• Material Science Analysis: Comparing the energy transfer efficiency of large-diameter rods versus smaller specimens to study scale effects in conduction.
• Heat Exchanger Engineering: Useful for students learning how copper’s high conductivity is utilized in industrial radiators and cooling fins.
