"Shiv Dial Sud & Sons"

A mess proof way to demonstrate waves and refraction in water.

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

Good quality, enameled cast iron tripods for supporting small objects over a burner.

Designed for Heavy Duty Student Use

The demonstrations feature the fundamentals of vacuum and air pressure as they describe how a pump works and how to find the mass and density of an air sample.

Grab and hold students' attention with these interactive and affordable demonstrations that show core physics concepts in action.

Perfect for density experiments, use this set determine the mass and volume of each sample and graph the mass versus volume. The slope of the straight line that results is the density of the material.
