Diaphragm Vacuum Pump - Chemical Resistant Oil-Free Pump - 30-60 L/min - 50 mbar

The Master Science PTFE Diaphragm Vacuum Pump is an oil-free pump built for corrosive gases and solvent vapours. The pump chamber is made of chemical-resistant materials and the diaphragm is PTFE-bonded, so it copes with aggressive media that would damage standard pumps.

It works with rotary evaporators of any brand, as well as concentrators, vacuum ovens and filtration units. Three versions are available with one or two heads and 30 or 60 L/min pumping speed.
