Oil-Free Vacuum Pumps for Lab Filtration: How to Size and Use Them

At a glance. Tech Inc. Oil-Free Vacuum Pumps supply clean vacuum for filtration sets, manifolds, SPE and degassing, with no oil to change.

Sizing

• One filtration set: a compact diaphragm pump is enough.

• Manifolds with several funnels: choose a higher flow.

• Solvent vapours: choose a chemical-resistant head.

Protecting the pump

• Fit a trap flask between filter and pump.

• Use the regulator to avoid tearing membranes.

• Run the pump briefly with air after solvent work.
