P E RI STA LTIC PUM P S Choosing the Right Pump for Your Application & Budget (continued) Harvard Apparatus offers an extensive selection of peristaltic pumps to suit the needs of a wide range of research applications. Pumps which offer features such as multi-channel pumping, computer control, analog control, low electrical noise and a wide range of fluid flow rates are now available. The following table was designed to answer most questions regarding our continuous flow pumps. Please contact our technical support department for further assistance. Peristaltic and Continuous Flow Pumps Traditional peristaltic pumps utilize a series of rollers to push fluid through tubing held within a pump head. Peristaltic flow is typically pulsatile, but can be made smoother with the use of more rollers in the pumping head. Our Mini-Peristaltic Pump (MPII, see page 61) features two speed ranges, reversability and dual channel pumping at a very reasonable price. Many pumps offer external control either through the input of an analog signal proportional to the speed or by RS-232 (serial) communication.
