Eisco Labs Bell in Acrylic Vacuum Jar Aparatus- Electric Bell Operates at 4-6V DC

EISCO vacuum jar with bell is used for acoustic study, and provides a vacuum environment for conducting experiments to demonstrate that sound requires air to travel through--as air decreases inside the jar, sounds disappear. The set includes an electric bell to generate sound during experiments, and the jar’s bottom flange has been ground flat for ensuring a tight seal. The jar is made of durable acrylic, which is lightweight, and resists shattering, impact, and most non-abrasive cleaners including ammonia and strong detergents. The jar requires a vacuum pump, and the bell operates on four 6V DC batteries (pump and batteries sold separately). The set contains a bell jar, electric bell, and a rubber cork with terminals. Rubber is highly elastic, and resists abrasion and impact forces. The jar measures 25.0 x 14.0cm (H x L). (H is height, the vertical distance from the lowest to highest point; L is length, the horizontal distance from left to right.) The set is suitable for high school or college students, or ages 14 to 21.

Science education products incorporate applied math and science principles into classroom and homeschool-based projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology.

EISCO Scientific manufactures and supplies lab equipment for education and industry. The company, founded in 1968 and headquartered in Rochester, NY, meets International Organization of Standardization (ISO) standard 9001: 2000.
