Vacuum chamber with a bell jar and an exhaust base
【Overall Advantages to Users】
This vacuum chamber is a conventional and common type.
The air in vacuum chamber can be exhausted using a vacuum pump.
The built in vacuum gauge shows the degree of vacuum inside.
Change the boiling point of materials
【To all users】
Easy to observe phenomena of matter in the vacuum condition inside of the chamber due to a glass bell jar.
Easy to do variety of experiments inside of the chamber due to a wider space of the exhaust base.
Easy to experiment the comparison of sound transferring in atmospheric and in vacuum condition.
Easy to observe that the conditions of air expansion under vacuum depends on that the size of a balloon in the chamber. The balloon is expanded by reducing the pressure of the chamber by a vacuum pump.
Pressure reduction boiling: Easy to observe changing the boiling point of water due to reducing air pressure in the chamber.
