Abstract
In a device for connecting apparatus for withdrawing ultrapure liquids from containers, the connection plate 4 is provided with three bores 5, 6, 7, of which two bores 5, 6 each extend through a socket 8 for vertical pipes. The top plate 9 has an integrated valve body 23 for accommodating at least two valve heads 2, 3 and three bores 10, 11, 12, which are congruent with the bores 5, 6, 7 of the connection plate 4. The bore 12 extends through the valve body 23, and the two other bores 10, 11 terminate, at one end thereof, in pipe sockets 29, 30, which project into the bores 5, 6 of the connection plate 4, and, at the other end thereof, in channels 31, 32, 33, 34 for the ultrapure liquids, which are arranged in the valve body 23 and are interrupted by the valve heads 2, 3.
