Multistage Roots vacuum pumps are a type of positive displacement pumps that utilize two or more intermeshing rotors to compress gas. They are commonly used in the analytical instrument applications for their high pumping speed, low ultimate pressure, and clean pumping environment. They can achieve high vacuum levels at lowest noise levels without the need for oil, leading to low maintenance and high reliability.
Introducing the nXLi and nXRi pumps from Edwards, designed for high-end mass spectrometry applications. The nXLi pumps offer enhanced performance and reliability, while the nXRi pumps feature a compact design, perfect for space-saving integration into analytical instruments and vacuum systems.
