Description
The Bell Jar with Plate is a classic laboratory apparatus used to conduct experiments under reduced-air conditions. The transparent jar allows the activity inside the chamber to be observed while the base plate provides a suitable surface for mounting experimental objects. It is especially useful for demonstrating that sound requires a medium to travel, as well as for introductory experiments involving air pressure and vacuum.
