The Air-Cooled Laboratory Rheostat is the classic lab solution for controlling voltages and currents.

The Eddy Current Experiment demonstrates Lenz's Law.

Glows with Characteristic Brilliance!

Small electrolysis apparatus with beaker included.

The 3D Magnet Viewer displays clear views of magnetic fields.

This demo features a cathode beam to explain the electromagnetic nature of electrons.

Students measure the voltages generated by a series of different pairs of half cells using the Electrolytic Bridge.

Great for classroom demonstrations involving power plants or conversion of energy.

This newly designed rheostat features a protective cover.

For class model building.
