Aspirator
An aspirator is a common piece of laboratory equipment. It provides a strong suction via the Venturi effect. It needs only a continuous stream of water to operate. The aspirator fits over a faucet and has a hose barb on one side. When water flows through the aspirator, gas will be sucked in through the hose barb. It is cheap to manufacture and operate.
