The Precision Linear Expansion Apparatus produces accurate determinations of the coefficient of expansion.

Both of these sets come with a roll-up style canvas storage pouch and a solid rubber activator.

For highly accurate samples when only minimal volumes are required, use this simple, stain-free apparatus.

This clamp features vinyl-coated swivel jaws made from stamped steel.

This complete set of materials makes possible multiple dramatic demonstrations of basic electrostatic principles.

The Current Balance is an excellent tool for studying electric currents.

The Moment of Force Apparatus contains everything needed to study principles of mass, levers, moments, forces, and equivalence.

A simpler version of the Advanced Pulley Demonstration Set, this model includes eight single pulleys and two double sheave pulleys in addition to EISCO ball bearing frictionless pulley.

The Specific Heat Specimens Set can be used to determine the specific heats of a variety of common metals.

The oscillatory platform can carry various masses and is free to oscillate in a horizontal plane under the restoring forces of two straight-blade spring supports.

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.

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

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