Product Description

Pumping disc

Product Introduction
The pumping disc is composed of an air extractor, a bell cover, an electric bell and a rubber seal ring. It must be used in conjunction with an air extractor or a dual-use air cylinder during the experiment.

Product Specification

Product name Pumping disc
Material plastic
Size 245*279mm

Demo Example
1. Sound propagation experiment
Place the bell cover on the air extraction plate with the sound of the electric bell. The clear electric bell can still be heard through the bell cover. Then, remove the air in the bell cover. The electric bell will gradually weaken until no sound can be heard. Close the valve of the air extraction plate and let the students observe that although the hammer of the electric bell is still ringing, no sound can be heard.

2 Low pressure boiling test:
Put a cup of hot water that has stopped boiling into the bell jar, and then extract air. You can see that the hot water in the cup is boiling again.

In addition, the instrument can also be used for experiments such as vacuum fountain, evaporation and icing, vacuum coating, and atmospheric pressure.

Product feature and application
This instrument can be used for various experimental demonstrations involving vacuum in physics teaching in middle schools and science teaching in primary schools.
Compared with the traditional products, the suction tray and bell jar developed by our factory have been improved in structure to achieve better experimental results. It is not necessary to apply grease on the rubber sealing ring in general experiments.
