Fisher Scientific FB65499 General Lab Compact Filtration Vacuum Pump Vakuumpumpe

Chemical-resistant vacuum pump consisting of N 820 G diaphragm vacuum pump, base plate, separator on (more) the suction side and high-performance condenser on the pressure side. Thanks to the high compatibility of steam and condensate, the system is perfectly suited for extremely aggressive/corrosive gases and vapours. Technical features Flow rate (max.): 20 l / min Final vacuum (max.): 6 mbar (abs.) Pressure (max.): 0.1 bar (rel.) Flow rate (m³/h) at atm. pressure: 1,2 Permissible fluid temperature between 5 and 40°C Valve material: FFPM Diaphragm material: PTFE coated Pump head material: TFM ™ PTFE Applications Distillation Rotary evaporation Multi-user vacuum systems Qualitative characteristics Vacuum system comprising chemically resistant diaphragm vacuum pump, base plate, separator on suction side and high performance condenser on pressure side Modular expandable 100% oil-free transfer Thereby pure transferring, evacuation and compression of gases High level of vapor and condensate compatibility Ideal for extremely aggressive / corrosive gases and vapors Integrated gas ballast valve 3-color status display for in operation / stand-by / error Integrated rotational speed control Environmentally friendly Start against ultimate vacuum of the pump Download the data sheet for further information and accessories.
