    What happens when a water aspirator is turned on?
    When the water aspirator is turned on the flow of water creates suction. The hose is part of the filtration system and should be heavy enough to prevent pinching or collapse under external atmospheric pressure. To filter a sample, turn on the aspirator and carry out the filtration in the same manner described for gravity filtration.
