The Dynamax RP-1 Peristaltic Pump is specifically designed for fluid transfer. The rotating head has ten stainless-steel rollers. As the head rotates, five of the rollers press the tubing up against the compression arm, producing flow by peristaltic action. Five rollers constantly in contact with the tubing ensures low pulsation, smooth flow, and high pressure. Model RP-1 is ideal for critical liquid chromatography, gradient generation, and flow analyzer applications.
