KNF Vacuum pump, LABOPORT®

Type N840G

The N 820 G and N 840 G feature a control knob for manual adjustments of the flow rate, making them well suited to a wide variety of applications. Thanks to the integrated rotational speed control, the pumps are quiet, very energy efficient, and can be optimally adjusted in accordance with the application.

The chemically resistant diaphragm pumps impress with their very small footprint and save valuable space in the laboratory. The next generation of LABOPORT® pumps are equipped with an easy-to-clean surface.
Potential applications include rotary evaporation, distillation, gel drying, degassing, use by vacuum ovens and vacuum concentrators.
