About Crookes Radiometer

Crookes Radiometer

We are a leading manufacturer, supplier, and exporter of Crookes Radiometers designed for physics laboratories, science museums, STEM learning centers, and educational institutions. This classic scientific apparatus demonstrates the effects of light energy and thermal radiation through the motion of lightweight vanes enclosed in a partially evacuated glass bulb.

The Crookes Radiometer consists of four mica vanes mounted on a low-friction spindle. Each vane is black on one side and silver on the other. When exposed to light, the vanes rotate, providing a fascinating demonstration of energy transfer and gas molecule interactions inside a low-pressure environment.

This apparatus serves as an excellent teaching aid for explaining concepts related to radiation, heat transfer, light energy, kinetic motion, and vacuum physics. Its attractive design also makes it ideal for classroom demonstrations, laboratories, science exhibitions, and educational displays.
