The invention relates to a An aseptic connector comprising a first connection unit (102； 202； 302； 402； 502) provided with a first terminal end surface (104； 204； 304； 404； 504) and a second connection unit (106； 206； 306； 406； 506) provided with a second terminal end surface (108； 208； 308； 408； 508)； said first and second terminal end surfaces are each provided with at least one first and second opening (110, 112； 210, 212； 310, 312； 410, 412； 510, 512), which openings are orientated to substantially coincide when said first and second connection units are connected to each other； said first and second openings are sealed by at least one film (114； 214； 314； 414； 514) arranged on said first and second connection units, so that the contact between the film and each connection unit is aseptic； said at least one film is adapted to be mated with a corresponding film on the other connection unit when said first and second connection units are connected to each other； and said mated films are adapted to be pulled out together two and two after mating such that corresponding first and second openings in said first and second terminal end surfaces are mated aseptically. At least two first ports (116； 216； 316； 416； 516) are arranged on the first connection unit, which first ports have fluid connection with the at least one first opening (110； 210； 310； 410； 510) in the first terminal end surface； and in that at least one second port (118； 218； 318； 418； 518) is arranged on the second connection unit, which the at least one second port has a fluid connection with the at least one second opening (112； 212； 312； 412； 512) in the second terminal end surface.
