Peristaltic pumping transports fluids efficiently, without risking contact with any portion of the pump itself. To accomplish this, flexible tubing is inserted between the pump rollers and housing. As the rollers rotate around a stationary rotor, the tubing is “squeezed” or occluded, pushing the fluid through the inside tubing surface. As the tubing behind each roller recovers its shape, a vacuum is created, drawing additional fluid in behind the occluded tubing. During this process, the fluid is contained entirely within the flexible tubing, eliminating exposure to any components of the pump and thus the risk of fluid contamination.
