Transfer device

A transfer device for enabling an optionally aseptic transition between a first object or a first process unit, and a second object or a second process unit, wherein the transfer device is capable of being installed at least partially in the first object and at least partially in the second object, the transfer device comprising:

• a first door element, which in the installed state is disposed on the first object, for opening and closing an access opening formed in a wall portion of the first object and leading to an interior of the first object;
• a second door element, which in the installed state is disposed on the second object, for opening and closing an access opening formed in a wall portion of the second object and leading to an interior of the second object;
• a locking apparatus for locking the first door element in a closed state and for releasing the first door element for opening the first door element, wherein the locking apparatus in the installed state is disposed in and/or on the first object;
• and
• an opener apparatus for opening and/or closing at least one of the door elements, wherein the opener apparatus in the installed state is disposed in and/or on the second object,
• wherein the first door element and the second door element are able to be brought to engage with one another and in the engaged state, when the first door element is released by means of the locking apparatus, are able to be conjointly removed from the access openings by means of the opener apparatus, so as to enable the transition, or the aseptic transition, between the first object and the second object.
