Air Cushion Plate

The air-cushion table is an ideal medium of instruction which can be used to clearly demonstrate a large number of experiments covering the following topics:
• Thermal motion of atoms and molecules in various states of aggregation
• Electrical conduction processes
• Models of atomic physics
• Mechanical motion
The air-cushion principle as well as the use of magnetic forces allow nearly zero-friction motion of hovering bodies. The equipment system is characterized by a clear and simple design, minimum preparatory adjustment requirements, clear visibility of all experiments through overhead projection, simple operation and high reliability.
The device consists of a robust frame with a pressure chamber whose cover plate is furnished with 1089 fine perforations and serves as an experimentation surface. Air is supplied to the pressure chamber by a blower via a hose, causing the colored bodies to hover. An additional air stream from an impulse valve makes it possible to alter the motion of the hovering bodies. The air-cushion table is equipped with two adjustment screws.

Dimensions: 350 mm x 350 mm x 75 mm

Lattice model with fixture
For demonstrating the principle of a crystal lattice, for example, during experiments on electrical conduction processes in semiconductors. The lattice model consists of a height-adjustable plexiglass plate from which 25 freely oscillating ceramic magnets are suspended.

Magnetic barriers
Magnetic barriers can be used to modify the plastic-bordered experimentation surface. This allows elastic collisions between the hovering bodies and the borders.

Magnetic hovering bodies
Hovering bodies moving on the air cushion simulate particle motion. The scope of delivery includes five different types consisting of transparent, colored plastic or aluminum capped with round ceramic magnets.

Electrodes
Two rod-shaped metal electrodes can be positioned in parallel with the experimentation surface in order to generate an electrical field. The effect of electrical fields on charged particles can also be simulated by inclining the experimentation surface.
