Water aspirators: Cheap pumps with environmental impact and high operating costs
28 Apr 2022Water 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.

PumpsLaboratory pumps are devices used to move liquids and gases by vacuum or positive displacement. The pressures/vacuums generated are determined by the type of pump used. High vacuum pumps include diffusion, ion, roots and turbopumps; for primary/medium vacuum applications see rotary vane pumps, scroll & diaphragm pumps. For the positive displacement of liquids explore a range of syringe and peristaltic pumps, as well as fluid aspirators.
