Lab Vacuum Pump System with Fast Solvent Recovery

KNF LABOPORT SH 820 G comprises a diaphragm vacuum pump, a base plate, a separator on the suction side, and a high-performance condenser on the pressure side — enabling fast solvent recovery.

It delivers a flow rate of up to 20 l/min, an ultimate vacuum of down to 6 mbar abs., and a pressure of up to 0.1 bar g.

Features and Benefits

Based on the award-winning N 820 G pump, the LABOPORT SH 820 G is a modularly-expandable laboratory vacuum pump system providing excellent performance with user-friendly features.

For example, a new three-color display is now built into the system, indicating the current status, allowing users to respond quickly to the process.

In addition, broad vapor and condensate compatibility, high chemical resistance, integrated gas ballast valve, and rotational speed control make the LABOPORT SH 820 G ideal for everyday laboratory practice.


Typical areas of use include distillation and rotary evaporation. KNF VC 900 is available to purchase for more precise vacuum control with an easy-to-use touch interface. Please contact us for details.
