KNF Neuberger N840

This used KNF Neuberger N840 is a diaphragm vacuum pump built for chemical-resistant, oil-free operation in demanding laboratory and process environments. The unit has been previously used and shows expected wear, but it remains functional and suitable for return to service. KNF's diaphragm technology is widely respected for delivering clean vacuum without the risk of oil back-migration or contamination, which is critical in sensitive laboratory workflows. The N840 model is frequently used in applications such as filtration, solvent evaporation support, gel drying, and vacuum ovens, where consistent vacuum levels and resistance to aggressive vapors are essential. Its rugged construction allows it to handle chemically aggressive gases and vapors better than many alternative pump technologies, making it a preferred choice in analytical and research laboratories. The pump's compact design also allows it to be easily incorporated into existing benchtop setups or larger system assemblies. This used pump is offered as a practical, budget-friendly option for laboratories and technicians needing a dependable vacuum source without the cost of new equipment. It is well suited to research labs, quality control departments, and equipment integrators who value KNF's reputation for durable, chemically resistant vacuum pump engineering.
