Crank it up! Put your students' excess energy to good use. Our high quality vacuum / pressure pump is a practical alternative to the flimsy plastic or expensive electric models on the market. Its heavy steel construction ensures it won't bounce around as lighter models might. It is geared to suck vacuum pressure through the same port regardless of which way the handle is cranked. This unit is ideal wherever a vacuum or pressure is required. Use it for experiments with vacuum tubes, vacuum filters, Magdeburg hemispheres, bell jars, density experiments, and many others.
