SW-2481 - ESAW Vibration Generator Provides mechanical oscillations when given input signals from an oscillator or AF oscillator. A specially designed coil system enables the unit to be operated at its maximum rang for a prolonged period without any damage due to overheating. The frequency respon...

WAVE MOTION APPARATUS This advanced apparatus demonstrates both longitudinal and transverse wave motions. Consisting of a number of eccentric discs supporting a series of metal rods revolving on a handle, transverse waves are obtained. Longitudinal waves are obtained from the bent rods with 24 pu...

SW-1749 - ESAW Vacuum or Pressure Apparatus Vacuum or pressure, the apparatus is a hand-operated device. It consists of a metal barrel with a piston and two nozzles for vacuum and pressure respectively. Can be used with vacuum plate PH36017

SW-1794 - ESAW Vacuum Metal Plate The top plate measures 11" in diameter and can be used with bell jars up to 9" in diameter. Constructed of cast iron, the plate is equipped with a 3/8" hose connection, vacuum release valve, and rubber gasket to provide a tight seal.

  ESAW Bell In Vaccum (SW-2120) Demonstrates that sound waves need material medium for propagation and cannot travel through vacuum. For use on pump plates with diameter at least 15cm. it consists of an electric Bell operating on 4-6 volts AC/DC, suspended inside bell jar through a pair of thick ...
