A '''water aspirator''', also called '''aspirator pump''', '''aspirator vacuum pump''', '''Venturi pump''', '''aspirator Venturi tube''' or simply '''aspirator''' is a type of ejector-jet pump, which produces vacuum by means of the Venturi effect. <br />
<br />
==Description==<br />
In an aspirator, fluid (liquid or gaseous) flows through a tube that first narrows and then expands in cross-sectional area. When the tube narrows, the fluid pressure decreases. In this narrow area the fluid velocity must increase to conserve mass continuity. Where the tube narrows, a vacuum is drawn because of the Venturi effect.<br />
<br />
It consists of a tee fitting attached to a tap and has a hose barb at one side. The flow of water passes through the straight portion of the tee, which has a restriction at the intersection, where the hose barb is attached. The vacuum hose should be connected to this barb.<br />
<br />
==Availability==<br />
Aspirators can be bought online or from lab suppliers.<br />
<br />
They are available in metal, plastic and glass.<br />
