Description

• 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 23.0 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.
