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. The RP-1 incorporates a unique cam design: the adjustment screw does not press the compression arm directly. Instead, turning the adjustment screw in the RP-1 moves a cam which applies gradual force to the compression arm. This results in more precise flow control and reduced tubing wear. RP-1 is powered by a high torque stepper motor, controlled by a microprocessor with unique feedback circuitry for good speed stability, even at very low flow rates. Speed stability is maintained between 0° – 40°C and against back-pressures of up to 5 bars. Pump speed is shown in revolutions per minute (rpm) on a liquid crystal display (LCD) on the pump front panel. Pump speed and direction of rotation are controlled by a membrane keypad next to the display. Several pump heads are available: a single-channel model and three multi-channel versions: 2-, 4-, and 8-channel. Individual tubing compression settings on the multi-channel pump heads allow different diameter tubing to be used for each channel. Independent compression settings for each channel ensure optimum flow rate and long tubing life. Fixed collars bonded to the tubing allow easy tube installation at the proper tension, in turn ensuring that the tubing diameter is optimized and not altered from day to day. Precise and accurate motor speed setting, correct tubing tension, and reproducible tubing diameter all contribute to ensuring reproducible flow rates.  
Came from a lab that was closing down run runs well. pumphead has one plastic lock missing should be an easy fix. Price has been adjusted because of missing piece.
