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.

The Four-in One-Hydraulic Kit can carry things like a glass of milk, toys, and other fun items.

Demonstrate the effect of pressure to water depth.

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.

Mounted on a wooden stand with a scale, the apparatus is comprised of a three-limbed glass tube with rubber tubing on the center.
