Water aspirators: Cheap pumps with environmental impact and high operating costs

Water Aspirators are a common way of creating a low-strength vacuum for many standard laboratory applications. Their simple design employs water running through a narrowing tube to create a reduced pressure via the Venturi effect. The cost of water coupled with the environmental impact of wasted water and solvent pollution need to be considered. In this application note, find out which other pump technologies are better suited for the environment, and why.
