Diaphragm vacuum pumps LABOPORT® N 820 G / N 840 G, chemically-resistant
The compact pumps feature a control knob for manual adjustments of the flow rate, making them well suited to a wide variety of applications, e.g. rotary evaporation, distillation, gel drying, degassing as well as the use with vacuum ovens and vacuum concentrators. Due to the manual rotational speed control, the pumps are quiet, very energy efficient, and can be optimally adjusted in accordance with the application.
-Easy-to-clean surface
-Adjustable in flow rate due to manual rotational speed control
-Combination of PTFE pump head and PTFE-coated diaphragm makes the pump ideal for extremely aggressive/corrosive gases and vapors
-High level of compatibility with vapor and condensation
