The ESAW Bell in Vacuum (SW-2120) is an essential apparatus for demonstrating the relationship between sound propagation and air pressure. When the air is evacuated from the chamber, the bell becomes inaudible—providing students with a compelling, real-time illustration of how sound requires a medium to travel. This classic demonstration is used in physics classrooms globally to explain acoustic principles and vacuum phenomena.
Manufactured in India by ESAW, this export quality lab equipment features a sturdy vacuum jar and bell assembly designed for repeat classroom use. The apparatus supports curriculum-based learning in CBSE/ICSE schools, international schools, colleges, and engineering institutions, and is suitable for bulk procurement by science education distributors across Africa, Europe, the Middle East, and the USA.
🎓 Ideal Use Case Scenarios:
-
Students: Grasp key physics principles with visual and auditory reinforcement.
-
Schools & Colleges: Used in classroom demonstrations on sound, pressure, and vacuum.
