Rethinking Everyday Practice: New Series of Lab Vacuum Pumps & Systems
KNF presents a new series of LABOPORT® pumps – N 96, N 820 G and N 840 G – delivering the well-known LABOPORT® performance with a striking new design for a streamlined lab routine. These new lab vacuum pumps expand upon the proven LABOPORT® pump innovations, including oil-free, non-contaminating and chemically resistant design, with a modern look. They offer the added benefit of speed-controlled DC motors for greater versatility.
In addition, the new LABOPORT® pumps are now also available as a system: Our models SH 820 G, SR 820 G, SH 840 G and SR 840 G are modular, compact and easy to use.
Clever and Elegant Lab Vacuum Pump Design for Easy Handling
When redesigning our successful LABOPORT® lab vacuum pump series, we gathered input directly from laboratory workers. We asked users what they looked for in daily lab work, enlisted experts to perform tests and incorporated their suggestions.
The result? Clever, elegant design with clear benefits in terms of handling and functionality.

New: Modular and Expandable Lab Vacuum Pumps
The new models SH 820 G, SR 820 G, SH 840 G and SR 840 G are configured to your individual needs, as an expandable lab vacuum pump system should be.
In addition to the features of the base pumps, they now come with the ability to extend the pump to a system with separators and a high-performance condenser. This allows for environmentally friendly recovery of solvents with excellent protection against aggressive chemicals.
