1 Introduction
1.1 The peristaltic principle
PF6 operates with a peristaltic dispenser head (tube pump), where the liquid only comes into contact
with the flexible tube, the tube connections and the filling nozzle. The tubes are usually made of
silicone, but other materials can also be used.
The dispenser head is designed in such a way that sterilized tubes can be mounted in the head
without affecting the sterility.
The dispenser head is self-priming, and the dispenser head itself can stand to be run dry (not
recommended for the sake of the tubes).
The dispenser head on PF6 works with two parallel tubes which are squeezed by rollers mounted on
ball bearings. The rollers in are offset in order to eliminate pulsation.
