  • the medium withdrawn by flushing with sterile air is pressed back into the bioreactor or the respective vessel so that no medium remains in the withdrawal line that would be exposed to other conditions over time than in the reactor itself. This ensures that the samples come completely from the interior of the bioreactor or the other vessel and are not contaminated by sample residues that have lingered in the line or the connector for a long time, even for later sampling.
  • the entire multi-connector port 100 is preferably designed to be sterilizable. It is also advantageous if all outer surfaces of the multi-connector port, in particular the membrane, are simple, for example can be sterilized by wiping with a cleaning fluid such as isopropanol or simply spraying or rinsing with such a cleaning fluid.
  • the Multi-Connector-Port 100 can be used to fill containers in a sterile manner, even outside of sterile working environments.

  • a sterile air curtain 792 is thus established around the tip via the nozzle device 790.
  • the flushing with sterile air can take place permanently or at least while the tip is penetrating until it has penetrated completely and as long as the tip is not penetrated.
  • FIG. 8 shows, in a detailed view, parts of an embodiment of a system according to the third aspect of the invention in two states.
  • the system shown here in parts comprises an encapsulation device in the form of a self-closing casing 890, which is designed here as a silicone cap with a cross slot, the silicone cap at one end facing away from an open end of the tip 880 an opening for receiving the tip on and at its opposite end facing the open end of the tip the cross-head.
  • the tip 880 of the handling system of the system is free and encapsulated from the ambient air by the self-closing jacket.
  • the tip 880 is pressed, for example, into a self-closing membrane 815, when the self-closing cover 890 and the self-closing membrane 815 come into contact, the self-closing cover is pressed open so that part of the tip 880 penetrates the self-closing membrane can, while the further parts of the tip 880 surrounded by the casing 890 remain protected by the latter.
  • the sheath 890, together with the self-closing membrane 815 then closes the tip off from the ambient air. As soon as the tip 880 is withdrawn, the sheath 890 wraps around the tip 880 again.
