Superconductor, 4-Point Wired

Product Code: SE-7734


Measuring the transition temperature of superconductors is one of the basic and most educational experiments in superconductivity and is now available to students with an easy and instructive experiment that is on par with state-of-the-art scientific research.

The 4-point Wired Superconductor includes a superconducting Bi-2223 bar with four wires attached to it. Students can experiment with 4-wire and 2-wire resistance measurements and learn how to measure the critical temperature of superconductors.

The superconductor is thermally attached to a metallic plate to which a Pt100 resistance thermometer is also attached. Please note that this product requires liquid nitrogen.
