Simple tool to explore the thermal properties of matter.

Employs Guericke’s Method for Demonstrating the Force of Atmospheric Pressure.

Demonstrate the Force of Air Pressure Without a Vacuum Pump

Ideal for demonstrating that vapor pressure increases when temperature increases.

Demonstrate the force of air pressure without a vacuum pump. The edges of the two 8.5 cm rubber cups are placed together and pressed to expel the air between them. Students discover the difficulty of separating the cups by pulling and tugging on the handles - providing an effective, 'hands-on' demonstration of air pressure.

This nickel coated plate uses a rubber pad to achieve air tight contact with a bell jar. It features a stopcock and center hole with safety screw plug and a rubber gasket.

High Quality for the Classroom.
