"VWR"

These free-running plastic pulleys are durable in design.

A set of eight coils wound on individual plastic spools. Each coil has two binding posts.

This working model thermostat will demonstrate how differential expansion is used to control temperature. A bimetallic strip is used to open or close an electric circuit when temperature changes. The contacts will carry about three amperes. The unit can be operated with a 6 V lantern battery, low voltage power supply, or a blow dryer. Mounted on a metal base; approximately 15 cm high.

This force table pulley includes a heavy-duty clamp and operates smoothly.

A Highly Effective Demonstration of Elastic Collision

Vivid Illustration of Thermoexpansion.

This launcher is easy to assemble, and it delivers consistent classroom results.

Economical and effective.

Ideal for Individual Study

Sized For Student Use.

The heavy base of the economy force table offers stability for all applications.

Demonstrate the conversion of mechanical energy into electrical energy by generating a static charge.

The construction of the multi-functional Demo Electric Motor is completely open.

With the Force Mechanism Trough, students can research acceleration and the effect of gravity on a moving body by propelling steel balls or a wood block down an aluminum trough track.

This is an excellent, inexpensive apparatus for experiments in precession, inertial guidance, and gyroscopic stabilization.
