Excellent Lab Vacuum Pump System

KNF LABOPORT SR 820 G is a laboratory vacuum pump system consisting of the award-winning N 820 G diaphragm vacuum pump, a base plate, and two separator flasks on the suction and pressure side.

Coping well with aggressive/corrosive gases and vapors, it offers 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.

The system permits exceptional compatibility of vapors and condensate while transferring, evacuating, and compressing media. It is 100% oil-free and maintenance-free.

Ergonomic and Customizable

As with other products in the newly-revised LABOPORT systems, the SR 820 G also sports several improvements to simplify and enrich daily laboratory processes.

First of all, the LABOPORT SR 820 G is modularly expandable. Users can purchase and install additional elements on demand, allowing for a custom-tailored vacuum system. 

Secondly, a three-color status display (in-operation, standby, and error) makes the process monitoring more user-friendly than ever. Last but not least, the streamlined, brand-new appearance is space-saving, easy to clean, and beautiful.
