Diaphragm vacuum pumps, LABOPORT®, N 840, N 842

Manufacturer: VWR


Single- or dual-head chemically resistant, dry running diaphragm pumps for a wide range of laboratory applications. They transfer and evacuate without affecting the media, i.e. media remains uncontaminated.

  • 100% oil-free displacement, so media cannot be contaminated by transfer, evacuation or compression
  • High resistance to vapours and condensates
  • Chemically resistant, suitable for use with very aggressive and corrosive gases and vapours
  • Maintenance-free, environmentally friendly; the pumps use no water and so produce no contaminated waste water

Application: Fluid aspiration, degassing, gel drying, rotary evaporation, centrifugal concentration, distillation

Includes diaphragm with patented tension optimisation, which allows the pump size to be smaller and extends the service life of the diaphragm. All parts that come into contact with the media are comprised of chemically resistant fluorinated plastics.

Ordering information: Includes chemically resistant diaphragm pump with thermal circuit breaker, mains fuse, connecting cable and PTFE hose attachments with for hoses with 10 mm internal diameter.
