Efficient combination of a pump and a vacuum plate.

Just a few strokes of the pump are enough to establish a vacuum in a bell jar, so students can observe the reducing sound level of the bell. The plate can also be used with electric vacuum pumps with the help of a three-way stopcock under the plate.
