Sterilizing apparatus for sterilizing disinfecting endoscope (1), the tunnel (4) having a first opening (5) and the second opening (6) on defining a tunnel (4) wall (7) tunnel (4) a first transverse wall which can be positioned in the first opening (5) so as to close the (11) tunnel (4) can be positioned in the second opening (6) so as to close the bath so as to be accessible for the endoscope insertion or removal the second lateral wall (12) such bath for receiving an endoscope to be sterilized (9) the tank supporting member (9) (9) of the tunnel (4) a first opening (5) from a first end run which projects to the outside (A1), the tank so as to be accessible for insertion or removal of the endoscope (9) in between the tunnel (4) second end run (A2) projecting out of the second opening (6) of, along the vessel line comprising a vessel support (10) and the tank (9) to the tunnel (4) provided with a guide means (8), for guiding on. When the tank (9) is located inside the tunnel (4), in order to sterilize the at least one endoscope, the upper wall (7), together with the tank (9), to form an enclosed chamber (13) first lateral wall when in the first opening (5) (11), alternatively, and releasably: rigidly constrained to the frame (2) so as to close the tunnel (4) the frame (2) whether the coupling or pulled rigidly constrained to the tank system, to allow that the tank system reaches the first end run (A1), the tank support member (10 ) and it can be linked second lateral wall when in the second opening (6) (12), alternatively, and releasably: rigidly constrained to the frame (2) is it so as to close the tunnel (4) is either connected to the frame (2) or, pulled rigidly constrained to the tank system, and allows the tank line reaches the second end run (A2) as will be, it can be connected to the tank support member (10).FIELD 4内視鏡を殺菌消毒するための殺菌消毒装置(1)は、第1の開口(5)及び第2の開口(6)を有するトンネル(4);トンネル(4)を画定する上壁(7);トンネル(4)を塞ぐように第1の開口(5)に位置決め可能な第1の横壁(11);トンネル(4)を塞ぐように第2の開口(6)に位置決め可能な第2の
