Lasts for Years!

Efficient combination of a pump and a vacuum plate.

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

Dramtically demonstrate the power of atmospheric pressure

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.

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