Abstract: The system comprising containment equipment is intended for the aseptic transfer of a powder, namely for emptying a container filled with powder into a collection container and/or for filling a container with powder from a storage container. The containment equipment has a working chamber surrounded by a housing. A robot is installed in the containment equipment, having an arm arrangement that moves over a pivot range. If there is a collection container it has an inlet leading from the working chamber, and if there is a storage container it has an outlet leading off into the working chamber. The container can be closed at least with a first closure element. A transfer head is mounted at the inlet into the collection container and/or at the outlet of the storage container, each protruding into the working chamber. The passive part forms the double flap together with an active part contained in the transfer head.
