An Inexpensive Recirculating Water Vacuum Pump for the Chemistry Laboratory
Cubberley, Mark S.; Hess, William A.; Johnson, Mark B.
Journal of Chemical Education, v97 n5 p1495-1499 May 2020
A recirculating water vacuum pump was constructed from inexpensive materials. The recirculating water vacuum pump has a smaller footprint compared to many commercial models and features a novel, 3D-printed water aspirator pump that also functions with a standard laboratory faucet connection. The performances of both the recirculating water vacuum pump and (faucet) water aspirator pump are comparable to commercial models. The total cost of the recirculating water vacuum pump is approximately $44, excluding the cost of a 3D printer and filament.
