Versatile Apparatus for Electrostatics Lessons.

Students Investigate Alternative Energy Forms

Operates 1/2 to 3 volts, 100ma start-up / runs at 15ma no load.  Strong torque - 300 RPM @ 1/2 volt. Great for gear drives.  2mm shaft dia. Size 1 1/4" dia x 1 1/4" long. 

Minature sockets for small bulbs.

The Large Wave form helix easily demonstrates wave phenomena.

Ice Melting Blocks are a unique way to teach principles of conductivity of heat and the scientific method.

A bare copper wire of the highest quality. Available in several standard AWG sizes.

A Classic Demonstration!

A Fascinating Demonstration!

Comprises an inverted “U” tube with its ends closed by sintered discs. For use in experiments involving the measurement of cell EMF under conditions of forward, zero and reverse current flow. The bridge comprises an inverted “U” tube with its ends closed by sintered discs. This apparatus provides a more effective method of making reversible cells then the wet filter paper or agar gel methods. Dia. of arms 13mm, overall width 80mm, overall height 100mm.

This lamp holder is suitable for miniature base lamps.

This pen provides a great platform for discovering, playing with, repairing, and designing electronics.

With this kit, students learn how acid-based titrations operate.

This extra large electroscope is ideal for classroom demonstrations of electrostatic principles. A lightweight metal vane is used as a pointer in the electroscope. This lightweight metal blade deflects when the electroscope plate is charged. A transparent scale is provided to measure the angle of the deflection. Front glass window slides up to allow insertion of ionizing material in chamber.

To Study the effects of friction using 4 different surface materials on a board.
