A: An aspirator is a device that makes a vacuum through the Venturi effect.
Q: How does an aspirator work?
A: Fluid flows through a tube in an aspirator, which causes the tube to become more narrow, increasing the speed of the fluid flow and decreasing the pressure, creating a vacuum.
Q: What is another name for an aspirator?
A: An aspirator can also be called an ejector or a filter pump.
Q: What is the most common type of aspirator used in laboratories?
A: The most common type of aspirator used in laboratories is the water aspirator.
Q: How is the vacuum hose connected to the water aspirator?
A: The vacuum hose is connected to the hose barb on the water aspirator.
Q: What limits the strength of the vacuum produced by a water aspirator?
A: The strength of the vacuum produced by a water aspirator is limited by the vapour pressure of the flowing water.
Q: Is the strength of vacuum produced by an aspirator limited if a gas is used as the working force?
A: No, the strength of vacuum produced by an aspirator is not limited if a gas is used as the working force.
