6.3 Assembly of Y-connectors
Since the dispenser head of PF22 is fitted with a double rotor, two suction tubes are used all the
way through the dispenser head. These two suction tubes are joined by a Y-connector. The Y-
connector should be placed as close to the filling nozzle as practically possible, for the best
precision and consistency in fillings.
Fig. 6.2
The selected tube is connected to a Y-connector as shown in Fig. 6.2. Since the Y-connectors are
made of polypropylene, the total tube system can be sterilised in an autoclave.
