About This Product
Steam heats one end of the copper rod and water flowing through the spiral tube takes heat from the other, so a steady temperature gradient forms along the rod. The heat carried away by the cooling water and the gradient along the rod give the conductivity. The felt-lined case surrounds the rod, and its front panel can be removed to check the set-up. Science Lab Export can supply the Searle’s Thermal Conductivity Apparatus to the United Kingdom, Trinidad and Tobago, Papua New Guinea, Lebanon and Malawi.
