KNF LABOPORT® N 840.3 FTP Diaphragm Vacuum Pump, 34 L/min, 6 torr; 115VAC, Cole-Parmer (CAT#: STEM-DS-0427-LC)

The Laboport® vacuum pumps include a solid-PTFE pump head, FFPM valves, and diaphragm with PTFE coation to provide excellent chemical resistance against the most corrosive gases and vapors. The pumps are intended for use in conjunction with rotary evaporators, vacuum ovens, and concentrators. Since the operation is 100% free of oil, it is easy to clean and maintain the pumps. The compact design allows the convenient transportation of the vacuum pump.
