Improved Formula for Higher Yields

Unit consists of a sturdy metal frame carrying a DC motor with an eccentric shaft for exciting the vibrations. Clamp the frame to a table, attach a string and then simply use masses and a pulley to put tension on the string.

Ideal for charging wet cell batteries, electroplating, electrolysis, and many other applications.

Closed Case Form Electroscope is enclosed, preventing air currents from affecting the deflection of the leaves.

The Air Core Solenoid is perfect for induced magnetic field studies.

The Magnetic Force on a Conductor demo show students how a current-carrying conductor behaves when placed in an external magnetic field.

The simple Atwood Pulley Machine features two pulleys connected to a sturdy rod.

These plates are for use in microchemistry experiments.

This new conductivity bar set features sensitive liquid crystal temperature indicators, which are attached to the front of each of four metal bars.
