Dispensing device

A device for dispensing sterile fluid comprises a chamber (73) which is selectively, sealingly, connectible with one of a first (59) and a second receiving station, a fluid inlet pipe (37) contiguous with a bellows chamber (83), a nozzle (77) contiguous with the other end of the bellow chamber (83) and a valve means (85) housed therein. The nozzle is movable between a retracted position out of sealing contact with the receiving station and an extended position to dispense fluid to the receiving station. The nozzle is biased to the retracted position and movable to the extended position in response to a first predetermined pressure in the sterile fluid being dispensed, and the valve means is openable by a second predetermined fluid pressure, greater than the first predetermined fluid pressure. The receiving station (59) comprises a block within the neck (61) of a bag (1) to be filled is clamped. The chamber (73), nozzle (77) and accessible exterior of block (59) are sterilised by microwaves.
