“…Low-cost and/or alternative apparatuses for laboratory tasks requiring vacuum have been reported in JCE − and elsewhere . In this paper, we describe the design of a 3D-printable water aspirator pump that functions effectively in a recirculating water vacuum pump or attached to a laboratory faucet, the construction of a recirculating water vacuum pump, and the performance testing of the recirculating water vacuum pump and (faucet) water aspirator pump against commercial models.…”

An Inexpensive Recirculating Water Vacuum Pump for the Chemistry Laboratory

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.
