A system (500) for transferring fluidic media comprises a holding unit (535) for holding a reservoir (580), the holding unit (535) being configured such that a plunger arm (594) that is connected to a plunger head (690) that is within the reservoir (580) is moveable when the holding unit (535) is holding the reservoir (580) and the reservoir (580) is being filled with fluidic media. The system has a vibrator (531) for vibrating the holding unit (535) so as to vibrate the reservoir (580) to cause any air bubbles within the fluidic media to travel upwards within the reservoir (580), and shake free, particularly while the reservoir (580) is being filled.
