Vacuum bell with plate Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12752
The Vacuum Bell with Plate by Educational Instrument India is a practical physics laboratory apparatus designed for demonstrating vacuum formation, atmospheric pressure, air pressure effects, and gas behavior. It is commonly used in school science laboratories, college physics labs, STEM classrooms, and educational training institutes.
This apparatus generally consists of a transparent bell jar placed on a strong base plate with a suitable sealing surface. When connected to a vacuum pump, air can be removed from inside the bell jar, creating a low-pressure environment for experiments and demonstrations.
The Vacuum Bell with Plate is useful for explaining important science concepts such as vacuum, atmospheric pressure, sound transmission, boiling under reduced pressure, expansion of gases, and air-supported phenomena. Its transparent bell jar allows students to clearly observe the experiment while the base plate provides stable support and proper sealing.
It is ideal for teacher demonstrations, student observations, and laboratory practicals related to pressure, vacuum, and general physics experiments.
