1. A peristaltic pump for pumping fluid in a plurality of cycles where each cycle has at least a first stage and a second stage, the peristaltic pump comprising:
a biased plunger biased toward a tube;
a first valve upstream of the biased plunger;
a second valve downstream of the biased plunger; and
an actuator configured to: engage and disengage from the biased plunger, open or close the first valve, open or close the second valve, and allow the biased plunger to move toward the tube to discharge fluid, wherein the actuator is further configured to:
in the first stage, open the first valve and move the biased plunger away from the tube, and
in the second stage, close the first valve, move the biased plunger toward the tube, and disengage the actuator from the biased plunger.
