Lasts for Years!

Efficient combination of a pump and a vacuum plate.

A perfect tool for studying density, specific gravity, and water displacement. The 250mL polypropylene overflow can with spout only requires a catch bucket for the overflow.

Durable shatter-proof plastic.

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.

Dramtically demonstrate the power of atmospheric pressure

All in one unit for studying pressure, temperature and volume of a gas and to demonstrate the relationship between them.

Draw connections between the displacement method for determining density and the bouyant force.
