Rpm-01 syringe pump is a perfect replacement of the peristaltic liquid pump to have liquid transferred continuously in high precision because of its special eccentric structure, besides, the
biocompatible fluid path makes this electric syringe pump corrosive resisting and non-contaminating to sample fluids, maintenance-free stepper motor driven system extend the service life to a
desirable level and ensure the strong reliability.
