Abstract
A multi-channel peristaltic pump in which each channel can be operated independently of the others. A peristaltic pump includes a plurality of motors, each of which drives a rotor shaft which is independently rotatable around an axis and which rotates a roller head having a plurality of rollers. The rotor shafts are disposed in a concentric manner. The peristaltic pump further can include a control system allowing an operator to selectively determine the speed and direction of rotation of each of the roller heads of the pump.
