Abstract: An aseptic sampling system comprises sampler and interface assemblies. Each assembly comprises a housing defining separate sterile enclosures. An air lock provides aseptic joining of the enclosures within the sampler and interface assemblies, and a re-sealable liquid connection mechanism operates within the lock. The sampler and interface assemblies, when connected, form an outer protective surface comprising the housings of the sampler and interface assemblies, the protective surface providing a sterile internal enclosure and air lock and an air-tight barrier between outer non-sterile, and inner sterile, atmospheres.

Abstract: A connector assembly has first and second connector bodies, a coupling mechanism arranged to couple the connector bodies at the first ends of the bodies, a moveable hollow piston, and a moveable actuator. The hollow piston moves from a first position to a second position in response to movement of the actuator from a first position to a second position. In the second position the hollow piston is sealed to the interiors of first and second connector bodies.
