KNF Laboport N 840.3 FT.18 Diaphragm Vacuum Pump for Corrosive Gases
Product Description
The KNF Laboport N 840.3 FT.18 is a chemically resistant diaphragm vacuum pump specifically designed for handling highly corrosive gases and vapors in laboratory environments. Its oil-free, contamination-free operation ensures reliable and clean vacuum generation essential for molecular diagnostics, bioprocessing workflows, and synthetic biology research.
- 100% oil-free design prevents sample contamination, critical in biotechnology and chemical analyses.
- Maximum flow rate: 34 L/min, providing efficient vacuum generation for applications such as vacuum filtration, rotary evaporation, and vacuum concentration in biotech labs.
- Final vacuum of 8 mbar (absolute) supports sensitive processes involving aggressive solvents and chemical vapor extraction.
- Constructed with PTFE pump head, PTFE-coated diaphragm, and FFPM valves offering excellent chemical resistance to aggressive and corrosive vapors common in biomanufacturing and molecular biology workflows.
- Quiet and reliable continuous operation supports long-duration experiments and bioprocessing setups.
- Compact benchtop design (weight 12.6 kg) enables easy integration on laboratory benches with minimal maintenance needs due to membrane technology.
- Suitable for laboratory temperature ranges (5 – 40 °C) with standard hose connections (Ø 10 mm inside).
This vacuum pump is widely adopted in biotechnology, pharmaceutical research, and chemical analysis where contamination-free vacuum performance and durability against aggressive chemical environments are paramount. It is essential for workflows in molecular cloning, live-cell imaging preparatory steps, and other applications demanding contamination-free vacuum conditions.
