MS 120 LC/MS Roughing Pump

MS 120 is a roughing (foreline) pump of choice for LC/MS instruments, designed for high pumping speed, low power consumption, and high stability in the 10-2 mbar pressure range

Due to the outstanding performance of this roughing pump, there is no need for multiple roughing pumps operating in parallel. The packaging and cart like design allow for a quick and easy installation. The pump is equipped with a built-in quiet cover for a silent operation.


Features

  • High pumping capacity – single package replacing two legacy oil pumps
  • Integrated quiet cover for silent operation, optimal cooling and reduced installation time
  • Inverter-driven motor allows speed and pressure adjustment, and reduced power consumption
  • Up to 1 year 24/7 operation without oil maintenance
  • Cart-like design reduces installation and maintenance time
