The MD 12 NT is an excellent choice for continuous, oil-free evacuation and pumping of non-aggressive gases especially for applications in physics and analytics. Due to the very good ultimate vacuum the MD 12 NT is often used as an alternative to rotary vane pumps, for example for vacuum ovens, for very quick and efficient degassing of viscous media, exhaust gas analytics and especially as backing pump for large turbomolecular drag pumps. The particularly high pumping speed enables the usage at bigger vacuum apparatus and with high gas throughput. The pump is extraordinarily silent and exhibits very low vibration making it an excellent choice on sensitive equipment such as electron microscopes. Back diffusion of oil or even oil back flow, e.g., into a high vacuum chamber is excluded due to its oil-free operation.
