Sterile connector for the sterile transfer of a liquid medium

A sterile connector for the sterile transfer of a liquid medium from a liquid container to a bioprocess engineering system,

• wherein the sterile connector has two coupling devices,
• wherein
• the coupling devices each have a housing having a housing interior and a control element which is adjustably mounted in the housing interior and forms a channel, wherein the channel extends through the control element from a control element inlet opening to a control element outlet opening, wherein the housing of one coupling device is configured to be mechanically connected to the housing of the other coupling device,
• wherein each housing has a fluid inlet and a fluid outlet which connect the housing interior to the surroundings, wherein, in the mechanically connected state of the housings, the fluid outlet of one housing and the fluid inlet of the other housing overlap,
• wherein, in the mechanically connected state of the housings, the control elements are each adjustable from a starting position, in which a fluid connection between the channel and the control element inlet opening on the one hand and between the channel and the control element outlet opening on the other hand is blocked, into an operating position, in which the control element inlet opening is fluidically connected to the fluid inlet and the control element outlet opening is fluidically connected to the fluid outlet.
