A tight transfer device (10) between two sterile volumes (12, 14), of the double door or port type (22, 26), is equipped with a decontamination system (44) using ultraviolet, pulsed ultraviolet or pulsed light radiation, of the facing points of the gaskets (30, 36) ensuring the necessary sealing action. This decontamination system (44) is integrated into one (20) of the flanges of the transfer device. It comprises a collar (46) made from a material able to diffuse radiation, as well as optical fibers (48), whereof one end is mounted on said collar. The other end of the optical fibers (48) is connected to a radiation source. When the source is used, the radiation, routed by fibers (48) over the entire periphery of the collar (46), diffuse into the same towards the points of the gaskets (30, 36) to be decontaminated.
Tight transfer device between two sterile volumes, including two flanges connectable to one another, two ports connectable to one another and to said flanges, and two annular gaskets respectively fitted to a first of the flanges and to the port connectable to the second flange, said gaskets having in cross-section V-shaped portions, whose points face one another when the ports and flanges are connected to one another, wherein into the second flange are integrated means for the decontamination, by ultraviolet, pulsed ultraviolet or pulsed light radiation, of the points of the V-shaped portions of the gaskets and immediately adjacent regions.
