Frequently Asked Questions
1. What are the main benefits of an oil-free laboratory pump?
Oil-free pumps provide a clean vacuum without the risk of oil back-streaming into your samples. They require significantly less maintenance and do not produce oily waste for disposal.
2. How do I choose between a standard and a chemical-resistant pump?
Standard pumps are suitable for air and non-corrosive gases. For applications involving solvent vapors or acids (like rotary evaporation), you must use a chemical-resistant pump with PTFE-coated parts to prevent internal damage.
3. What does "multi-stage" mean in a vacuum pump?
Multi-stage pumps, such as the KNF N 840.3 series, use multiple diaphragms in series to achieve much deeper ultimate vacuum levels compared to single-stage units.
4. Can I use these pumps for continuous operation?
Yes, professional units from Vacuubrand and KNF are engineered for long service life and continuous duty cycles, making them ideal for overnight filtration or long-duration distillation processes.
