The ESAW Bell in Vacuum Apparatus (Model PSWO-3006) is an essential educational tool used to demonstrate how sound requires a medium to travel. This physics demonstrator is ideal for practical demonstrations in classrooms, colleges, science labs, and engineering institutions worldwide.
With a glass bell jar mounted on a robust base and an electric bell suspended inside, this setup allows educators to clearly showcase sound propagation in air versus vacuum. As air is gradually evacuated using a vacuum pump (not included), the sound of the bell fades—making it perfect for visual and auditory learning in acoustics, wave theory, and vacuum science.
Whether you're running a school lab in India or a research centre in the USA, the ESAW Bell in Vacuum Apparatus offers affordable, export-quality lab equipment for physics education.
🎓 Practical Use Scenarios:
-
Students: Understand sound transmission and medium dependence.
-
Schools & Colleges: Conduct sound and vacuum-related physics experiments.
-
Science Labs & Chemistry Labs: Demonstrate atmospheric pressure concepts.
-
Engineering & Medical Colleges: Support physics foundation in technical courses.
-
Industrial Labs & R&D Centres: For training, testing, or display experiments.
