KNF Laboport SH 820 G Chemical-Resistant Diaphragm Vacuum Pump System

The KNF Laboport SH 820 G is a chemical-resistant diaphragm vacuum pump system designed for reliable evacuation and compression of highly aggressive and corrosive gases and vapors. This modular vacuum pump unit features a diaphragm vacuum pump (N 820 G), a base plate, a separator on the suction side, and a high-performance condenser on the pressure side, enabling compatibility with steam and condensate critical in harsh chemical environments.

Key technical specifications include:

• Max flow rate: 20 l/min (1.2 m³/h at atmospheric pressure)
• Final vacuum: 6 mbar (absolute)
• Max pressure: 0.1 bar (relative)
• Valves: FFPM material
• Diaphragm: PTFE coated
• Pump head: TFM™ PTFE
• Permissible fluid temperature: 5 to 40 °C

Additional functional features:

• 100% oil-free gas transfer ensures pure vacuum generation, essential in molecular diagnostics and synthetic biology workflows requiring contamination-free environments.
• Integrated gas ballast valve improves handling of condensable vapors, making this pump ideal for rotary evaporation and distillation processes in bioprocessing and biomanufacturing.
• 3-color status display and integrated motor speed control facilitate easy monitoring and adjustment, supporting multi-user vacuum systems in research laboratories.
• Environmentally friendly design supports sustainable laboratory operations in biotechnology and pharmaceutical research.

This vacuum pump system is widely adopted in biotechnology and chemical research fields for aggressive gas handling, essential in applications such as synthetic biology, gene editing setups, and molecular cloning workflows requiring robust and contamination-free vacuum technology.
