KNF LABOPORT N 842.3 FT.18 Chemical-Resistant Diaphragm Vacuum Pump
Product Description
The KNF LABOPORT N 842.3 FT.18 is a robust, oil-free diaphragm vacuum pump specifically engineered for laboratory environments requiring high chemical resistance and contamination-free operation. Utilizing advanced KNF membrane technology and corrosion-resistant materials such as PTFE pump heads, PTFE-coated diaphragms, and FFPM valves, this pump maintains stable vacuum performance essential for biotechnology and chemical research applications involving aggressive gases and vapours.
Key technical features include:
- 100% oil-free membrane technology, ensuring no risk of sample contamination critical to molecular diagnostics and bioprocessing workflows
- High chemical resistance to corrosive gases, making it optimal for biopharmaceutical production pipelines and synthetic biology research
- Compact and quiet design suited for benchtop lab setups in pharmaceutical and analytical chemistry labs
- Maximum flow rate approximately 34 L/min and a final vacuum of around 2 mbar (absolute), supporting applications such as vacuum filtration, rotary evaporation, degassing solutions, and dehydration under controlled conditions
- Operating temperature range from 5 to 40 °C enables stable performance across typical laboratory environments
- Low maintenance requirements combined with a long service life reduce downtime in demanding research settings
This vacuum pump is widely adopted in chemical, pharmaceutical, and biotechnological laboratories for applications including vacuum filtration, rotavapor-assisted solvent removal, and vacuum extraction of chemical vapours. Its reliable, oil-free operation and chemical-resistant construction make it an essential instrument for live-cell imaging sample preparation, molecular cloning workflows, and biomanufacturing process optimization.
