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.
