The conduit is connected to at least one intermediate stage of the high-vacuum pump () in addition to the pre-vacuum zone of the high-vacuum pump () via conduit sections () and valves (). A housing (), in which at least some of the conduits and valves and the high-vacuum pump () are integrated, forms part of the leak detector () and a detachable slide-in module () forms part of the high-vacuum pump. The slide-in module has an external jacket construction () comprising passages () and when the leak detector () is operational, is situated in a receiving opening () that is provided in the housing ().
