The vacuum plate with a bell is intended for demonstration of experiments in a closed volume with rarefied air. The plate is equipped with a bell, which is used in the experiment to demonstrate the propagation of sound oscillations in vacuum

The device consists of a plastic base with a faucet, a bell made of thick glass, a rubber gasket and an electric bell. During the experiments, a pump hose is connected to the tap located in the base of the plate and the air is pumped out, thus creating a vacuum under the dome.
